abstract = {This paper illustrates the software suite developed for Track 1 of the IPIN
competition, which evaluates smartphone apps for indoor localization. Com- petitors have one
day before the trial day to survey the competition area. On the trial day, an independent
“actor” carries the competing system on smartphone and walks a predefined path. Competing
systems provide contin- uous location estimates, which are later compared to a ground
truth. We de- scribe the software suite used to gather and present the results: the StepLog-
ger Android application for real-time logging of position estimates and the EvaalScore tool
for performance evaluation. StepLogger collects timestamped location data from competitors,
while EvaalScore calculates the accuracy of the competing systems. The competition ranking is
based on the third quartile of point localization error. The presented soft- ware suite
ensures a standardized and fair assessment of competing systems, thus promoting
reproducibility and transparency in indoor localization re- search.},

abstract = {Indoor positioning is a thriving research area which is slowly gaining market
momentum. Its applications are mostly customised, ad hoc installations; ubiquitous
applications analogous to GNSS for outdoors are not available because of the lack of generic
platforms, widely accepted standards and interoperability protocols. In this context, the
Indoor Positioning and Indoor Navigation (IPIN) competition is the only long-term, technically
sound initiative to monitor the state of the art of real systems by measuring their
performance in a realistic environment. Most competing systems are pedestrian-oriented and
based on the use of smartphones, but several competing Tracks were set up, enabling comparison
of an array of technologies. The two IPIN competitions described here include only off-site
Tracks. In contrast with on-site Tracks where competitors bring their systems on site – which
were impossible to organise during 2021 and 2022 – in off-site Tracks competitors download
pre-recorded data from multiple sensors and process them using the EvaalAPI, a real-time,
web-based emulation interface. As usual with IPIN competitions, Tracks were compliant with the
EvAAL framework, ensuring consistency of the measurement procedure and reliability of
results. The main contribution of this work is to show a compilation of possible indoor
positioning scenarios and different indoor positioning solutions to the same problem.},

Arduino to monitor the usage of domestic appliances in real-time: Enerduino-pro. The design
uses low-cost easy-to-assemble open-source electronic components and consists of four main

(for debugging purposes only). We describe the device, complete with open software and

abstract = {IPIN 2019 Competition, sixth in a series of IPIN competitions, was held at the
CNR Research Area of Pisa (IT), integrated into the program of the IPIN 2019 Conference. It
included two on-site real-time Tracks and three off-site Tracks. The four Tracks presented in
this paper were set in the same environment, made of two buildings close together for a total
usable area of 1000 m² outdoors and and 6000 m² indoors over three floors, with
a total path length exceeding 500 m. IPIN competitions, based on the EvAAL framework,
have aimed at comparing the accuracy performance of personal positioning systems in fair and
realistic conditions: past editions of the competition were carried in big conference
settings, university campuses and a shopping mall. Positioning accuracy is computed while the
person carrying the system under test walks at normal walking speed, uses lifts and goes up
and down stairs or briefly stops at given points. Results presented here are a showcase of
state-of-the-art systems tested side by side in real-world settings as part of the on-site
real-time competition Tracks. Results for off-site Tracks allow a detailed and reproducible
comparison of the most recent positioning and tracking algorithms in the same environment as
the on-site Tracks.},

abstract = {Indoor Positioning Systems suffer from a lack of standard evaluation
procedures enabling credible comparisons: this is one of the main challenges hindering their
widespread market adoption. Traditionally, accuracy evaluation is based on positioning errors
defined as the Euclidean distance between the true positions and the estimated
positions. While Euclidean is simple, it ignores obstacles and floor transitions. In this
paper, we describe procedures that measure a positioning error defined as the length of the
pedestrian path that connects the estimated position to the true position. The procedures
apply pathfinding on floor maps using Visibility Graphs or Navigational Meshes for vector
maps, and Fast Marching for raster maps. Multi-floor and multi-building paths use information
on vertical in-building communication ways and outdoor paths. The proposed measurement
procedures are applied to position estimates provided by the Indoor Positioning Systems that
participated in the EvAAL-ETRI 2015 competition. Procedures are compared in terms of
pedestrian path realism, indoor model complexity, path computation time and error magnitudes.
The Visibility Graphs algorithm computes shortest distance paths; Navigational Meshes produces
very similar paths with significantly shorter computation time; Fast Marching computes longer,
more natural-looking paths at the expense of longer computation time and memory size. The
75\textsuperscript{th} percentile of the measured error differs among the methods from 2.2~m
to 3.7~m across the evaluation sets.},

many people are gathered together. In the described experimentation with sniffing devices we
adopted fingerprinting interpolation, which requires no survey phase and automatically adapts
to changes in the environment. The same process can be carried out using the Wi-Fi access
points already installed in the environment, thus allowing for operation free of installation,

abstract = {In recent years, indoor localization systems have been the object of
significant research activity and of growing interest for their great expected social impact
and their impressive business potential. Application areas include tracking and navigation,
activity monitoring, personalized advertising, Active and Assisted Living (AAL), traceability,
Internet of Things (IoT) networks, and Home-land Security. In spite of the numerous research
advances and the great industrial interest, no canned solutions have yet been defined. The
diversity and heterogeneity of applications, scenarios, sensor and user requirements, make it
difficult to create uniform solutions. From that diverse reality, a main problem is derived
that consists in the lack of a consensus both in terms of the metrics and the procedures used
to measure the performance of the different indoor localization and navigation proposals. This
paper introduces the general lines of the EvAAL benchmarking framework, which is aimed at a
fair comparison of indoor positioning systems through a challenging competition under complex,
realistic conditions. To evaluate the framework capabilities, we show how it was used in the
2016 Indoor Positioning and Indoor Navigation (IPIN) Competition. The 2016 IPIN competition
considered three different scenario dimensions, with a variety of use cases: (1) pedestrian
versus robotic navigation, (2) smartphones versus custom hardware usage and (3) real-time
positioning versus off-line post-processing. A total of four competition tracks were evaluated
under the same EvAAL benchmark framework in order to validate its potential to become a
standard for evaluating indoor localization solutions. The experience gained during the
competition and feedback from track organizers and competitors showed that the EvAAL framework
is flexible enough to successfully fit the very different tracks and appears adequate to
compare indoor positioning systems.},

abstract = {{Ambient Assisted Living} applications are deployed in smart environments that
provide some basic services, a typical example being user localization. {AAL} applications
generally have low accuracy requirements for indoor localization; this opens the opportunity
for parasitizing the existing smart environment infrastructure without adding dedicated
positioning sensors. In this scenario, one can exploit simple binary sensors that are usually
present in the smart environment, such as light and appliance switches or intrusion detection
sensors, to obtain a rough estimate of the position of the user. This application is
device-free, meaning that the user is not required to carry any device in order to be
localized. In this paper we present {CEO}, a software-only system which we evaluate along the
technical guidelines of the {EvAAL} competition. While the localization performance of {CEO}
is lower with respect to most {EvAAL} competitors of past editions, it has the benefit of
being non-intrusive, easy to install and perfectly compatible with other software systems:
these characteristics would made it a potentially significant {EvAAL} competitor. While
developing {CEO}, we only exploited the definition of the {EvAAL} competition environment as
it was presented to competitors. The only inputs to {CEO} are the context events generated
during the competition, which in 2012 and 2013 were limited to pressing light switches and
using a stationary bicycle. We compare the performance of {CEO} against the results of those
editions of {EvAAL} and show how it can be used to easily improve the performance of any

challenging due to the complexity of such systems and to the variety of solutions adopted and

for solutions. On the other hand, analyzing and comparing {AAL} solutions is paramount for the
assessment of the research results in this area. {EvAAL} (Evaluating {AAL} Systems Through
Competitive Benchmarking) is a recently established international competition that aims to
address this problem in order to let benchmarking and comparison methodologies of {AAL}
systems emerge from experience. This work describes the first {EvAAL} competition which was
devoted to localization and tracking; proposed evaluation criteria, benchmarks, and achieved
results are reported. All evaluation data are freely available from the {EvAAL} web site.},

average expected delay experienced by the clients. Two different channel error models are
considered: the Bernoulli model and the simplified Gilbert-Elliot one. In the former model,
each packet transmission has the same probability to fail and each transmission error is
independent from the others. In the latter one, bursts of erroneous or error-free packet
transmissions due to wireless fading channels are modeled. Particular cases are detected where
optimal solutions can be found in polynomial time. For general cases, simulations show that
good sub-optimal solutions can be found on benchmarks whose item popularities follow Zipf
distributions.},

flows, calls for a robust and ubiquitous end-to-end multimedia congestion control mechanism,
such as TCP Friendly Rate Control (TFRC) that provides fair sharing with the other Internet
traffic. This paper therefore analyses the implications of using rate-adaptive congestion
control over satellite links that utilise Demand Allocation Multiple Access (DAMA) to maximise
satellite transponder utilisation. The interaction between TFRC with DAMA is explored using
simulations supported by fluidic flow models. The analysis shows that DAMA slows-down the
start-up phase of TFRC, causing non- negligible delays. To mitigate this problem, we propose a
new cross-layer method based on the Quick-Start (QS) mechanism. This can accelerate the
start-up of multimedia flows by judicious allocation of additional capacity derived from
cross-layer signalling.},

abstract = {Designing efficient transmission mechanisms for advanced satellite networks is
a demanding task, requiring the definition and the implementation of protocols and
architectures well suited to this challenging environment. In particular, transport protocols
performance over satellite networks is impaired by the characteristics of the satellite radio
link, specifically by the long propagation delay and the possible presence of segment losses
due to physical channel errors. The level of impact on performance depends upon the link
design (type of constellation, link margin, coding and modulation) and operational conditions
(link obstructions, terminal mobility, weather conditions, etc.). To address these critical
aspects a number of possible solutions have been presented in the literature, ranging from
limited modifications of standard protocols (e.g. TCP, transmission control protocol) to
completely alternative protocol and network architectures. However, despite the great number
of different proposals (or perhaps also because of it), the general framework appears quite
fragmented and there is a compelling need of an integration of the research competences and
efforts. This is actually the intent of the transport protocols research line within the
European SatNEx (Satellite Network of Excellence) project. Stemming from the authors' work on
this project, this paper aims to provide the reader with an updated overview of all the
possible approaches that can be pursued to overcome the limitations of current transport
protocols and architectures, when applied to satellite communications. In the paper the
possible solutions are classified in the following categories: optimization of TCP
interactions with lower layers, TCP enhancements, performance enhancement proxies (PEP) and
delay tolerant networks (DTN). Advantages and disadvantages of the different approaches, as
well as their interactions, are investigated and discussed, taking into account performance
improvement, complexity, and compliance to the standard semantics. From this analysis, it
emerges that DTN architectures could integrate some of the most efficient solutions from the
other categories, by inserting them in a new rigorous framework. These innovative
architectures therefore may represent a promising solution for solving some of the important
problems posed at the transport layer by satellite networks, at least in a medium-to-long term
perspective.},

performance is significantly impaired by apparently low values of the bit error
rate. Generally speaking, on a wireless link bandwidth can be traded for information quality

correction. On this basis, we show a general method of taking advantage of this trade-off in

abstract = {Network services with deterministic guarantees are based on a worst-case
description of user-generated traffic. When designing a policing and scheduling algorithm for
guaranteed services on the Internet, accuracy of description of the traffic profile has to be
traded with simplicity of implementation. The result of this trade off is often expressed as
the number of token buckets required by the service along with the choice of their
parameters. The GS type of service proposed by the IETF uses two token buckets both for
characterizing the traffic and for policing it. The choice of using only two token buckets is
primarily driven by policing costs. In this paper we propose a method that allows the number
of token buckets used for characterizing the traffic to be greater than what is actually
needed to police it. This means we can obtain an accurate profile of the traffic while keeping
policing simple. The method consists of computing a profile of the traffic which involves a
number of token buckets of the order of ten, and then doing the policing using only the first
token bucket, plus another one which is chosen depending on the delay requirements of the
receivers. This paper shows that with this simple enhancement we obtain a guaranteed service
whose performance closely approaches the theoretical limits of services with deterministic
guarantees.},

abstract = {This paper describes a complete fade countermeasure system, designed for thin
route user-oriented and fully meshed satellite networks. The signal degradation due to the
residual uplink attenuation after up-power control intervention, plus the down-link
attenuation, is compensated for by varying the FEC coding and bit rates of the data. Down and
up-link signal degradations are evaluated separately: the former by collecting statistics of
quantised levels of the demodulated PSK signal, and the latter by using a narrow band signal
level estimator. Measurement times are optimised using a model to evaluate the scintillation
variance. The performance evaluation of the whole system in the presence of additive white
Gaussian noise (AWGN), shows that very small link power margins can be adopted.},

possible to trim the required bandwidth in continuous mode in the working range, thus saving
some bandwidth when keeping the video quality constant during changing fade conditions. The
performances of DRS applied to both the non-scalable and the scalable MPEG-2 coded video

are built-in, while others can be designed from scratch and added without much effort. The
parameters of the built-in allocation policies can easily be changed in order to exploit the
full potential of the allocation schemes. Fracas' features permit the optimisation of
satellite resource usage in accordance with the traffic pattern supported. Fracas enables
research teams and students to explore and compare different multiple access schemes, and to
develop simulation runs for various kinds of service-induced traffic, including aggregate

the plot of attenuation versus time recalls the behaviour of a self-similar process. We then
make various considerations and propose a fractional Brownian motion model for the
scintillation process. We describe the model in detail, with pictures showing the apparent
self-similarity of the measured data. We then show that the Hurst parameter of the process is
a simple function of the rain fade. We describe a method for producing random data that
interpolate the measured samples, while preserving some of their interesting statistical
properties. This method can be used for simulating fade countermeasure systems. As a possible
application of the model, we show how to optimise fade measurement times for fade

abstract = {Variable Bit Rate (VBR) video is currently by far the most interesting and
challenging real-time application. A VBR encoder attempts to keep the quality of video output
constant, and at the same time reduces bandwidth requirements since only a minimum amount of
information has to be transferred. On the other hand, as VBR video traffic is both highly
variable and delay sensitive, high-speed networks (e.g. ATM) are generally implemented by
assigning peak rate bandwidths to VBR video applications. This approach may however be
inefficient in a satellite network based on a TDMA scheme. To overcome this problem, we have
designed a demand-assignment satellite bandwidth allocation algorithm in TDMA, named V2L-DA
(VBR 2 Level-Demand Assignment), which manages the VBR video traffic according to a dynamic
bandwidth allocation algorithm. In this paper we discuss how to tune the proposed algorithm in
order to optimise network utilisation when MPEG-1 VBR video traffic is being transmitted. Our
results indicate that most of the time only 40\% of the peak rate bandwidth is needed to
satisfy the VBR source, and the remaining 60\% of the peak rate bandwidth can be used to
transmit the datagram traffic queued in the network stations.},

and its associated variable data rate modem enables users to implement very complex frame
structures under software control. Burst rates of 512 Kbit/s - 8.192 Mbit/s and different
coding rates are possible allowing the transmitted bit energy from each station in the network
to be adapted to prevailing conditions. The proposed application of the station is the
transmission of mixed stream and packet traffic, in a LANs interconnection via satellite
environment, using a modification of the FODA 5 technique. The association of the up-link
power control feature with the bit and coding rate variation gives the system an interesting
ability to cope with fade conditions. The link outage probability is investigated for the
Olympus transponder in Ka band. The ability of the system, together with the good performance
of Olympus, shows that the Ka band is usable for the above mentioned types of networks without
prohibitive fade degradation, at least for limited coverages.},

industrialised nations and a key issue on Europe's agenda for the period 2014-2020. The number
of people aged 60 and over in the {EU} is now rising by more than two million every year. This
raises the question of how to transform this challenge to our societies into a driver of
economy and create a win-win situation? One of the envisioned solutions is the application of
assistive technology combined with newly created services to allow people to live an
independent life for as long as possible. Research in this area involves many {ICT} related
{R&D} disciplines and has attracted much attention in the last couple of years. Several
initiatives have emerged to tackle the challenges involved, and significant incremental
progress has been made on many fronts. But a major breakthrough, leading to a standardised
approach and thereby to widespread adoption, is still not in sight. One of the main problems
from the technological point of view is fragmentation. The mission of {AALOA}, the {Ambient
Assisted Living Open Association}, is to address this situation by bringing together the
resources, tools and people involved in {Ambient Asssisted Living (AAL)} in a single forum
that makes it much easier to reach conclusions on provisions needed to achieve progress. A
concrete technical objective is to promote a common platform or middleware that is distributed

not require any special hardware and is available in most standard wireless

consumption, sensor size, and cost. In front of these interesting characteristics, the
performance of the RSSI approach is worst with respect to some more invasive ad hoc hardware
range-based solutions (such as Angle of Arrival, Time of Arrival etc...). Context information,
such as knowledge of being in a given room, can increase the localisation accuracy of
RSSI-based methods. In this paper we propose a localisation method that leverages context

presence of unrecoverable channel transmission errors. The objective is that of minimizing the
average expected delay experienced by the clients. Two different channel error models are
considered: the Bernoulli model and the simplified Gilbert-Elliot one. In the former model,
each packet transmission has the same probability to fail and each transmission error is
independent from the others. In the latter one, bursts of erroneous or error-free packet
transmissions due to wireless fading channels are modeled. For both channel error models,
optimal solutions can be found in polynomial time when all data items have unit lengths, while
heuristics are presented when data items have non-unit lengths. Extensive simulations,
performed on benchmarks whose item popularities follow Zipf distributions, show that good
sub-optimal solutions are found.},

mostly relevant. The chapter provides an overview on criteria used to evaluate the performance
of localization system, followed by an overview of technologies used for different types of
sensors and general ways to fuse data generated by sensors. Since we envision a future where
the presence of small devices communicating via packet radio is ubiquitous in most indoor and
some outdoor environments, the rest of the chapter concentrates on methods and algorithms used
in the context of wearable radios, most of which are based on the RSS (received signal
strength) indicator available on packet radio devices.},

presence of unrecoverable channel transmission errors. The behavior of wireless channels is
described by the Bernoulli model, in which each packet transmission has the same probability
to fail and each transmission error is independent from the others. The objective is that of
minimizing the average expected delay experienced by the clients. Optimal solutions can be
found in polynomial time when all data items have unit lengths, while heuristics are presented
when data items have non-unit lengths. Extensive simulations, performed on benchmarks whose
item popularities follow Zipf distributions, show that good sub-optimal solutions are found.},

defined a reference model of a simulation process. According to the needs we have developed a
software tool CostGlue, which represents a central repository for data produced with different
types of simulation tools and acts as a converter of different output formats into different
input formats. CostGlue has modular software architecture. This enables further development
and contributions from any other research sphere of activity. The core of the software tool
represents the application CoreGlue responsible for communicating with the database. CoreGlue
represents unified interface for writing to the database and reading from it. Specific
functions like import and export of data and different mathematical calculations are
represented as a set of self-described modules, which are loaded as necessary. The graphic
user interface is introduced as a web application for the simplicity of use and effective
remote access to the application. The software package CostGlue is going to be released as

abstract = {Complex communication systems where satellite links are involved are difficult
to test and tune up without the help of simulation tools. First of all, using satellites is
very expensive - the satellite time spent in testing and tuning-up the system must thus be as
short as possible. Second, during the performance evaluation in a real environment it is not
always possible to find the right amount of traffic, and the most appropriate traffic pattern
and data aggregation that will put the system under the maximum amount of stress so that its
limits can be validated. When satellite constellations are involved, rather than single
satellites, these problems are enormously exacerbated, to the point that in all but very
particular cases it is practically impossible for the researcher to do tests on satellite
constellations. It is therefore necessary to use some kind of simulation tool. The array of
required features for the tool is very broad. The basic feature is that of making it possible
to describe the constellation topology, and the position of earth terminals. Satellite may
have different capabilities, in term of number and characteristics of intersatellite links,
spot topology and behaviour, and on-board processing abilities. Many types of routing
algorithms are under study, some of which allow for dynamic rerouting based on nodes'
perceived congestion or on quality of service requests. Also, it should be possible to analyse
channel allocation algorithms for the up-down links, including frequency reuse algorithms. The
traffic generation choice should be broad and easily extensible, allowing for both fine
control on single connections and generation of background traffic for loading the satellite
network. Finally, a rich set of statistic collection and analysis tools should be available.},

this end, we look at the best performers in the smartphone-based Tracks of IPIN competitions.
This selection is particularly severe and significant, as this competition Track is performed
live, without an opportunity for competitors to instrument or prepare the site or to know the
path in advance and with only two attempts allowed, of which the best result is taken. An
independent actor holds in hand the smartphone running the competing system, and results are
downloaded from the phone immediately after the competition path is completed, without any
post-processing. We show how sensing technologies have evolved from 2014 to 2019 and show a
trend towards improving accuracy performance. Last, we provide insight in the role that
sensors and algorithms play in the evolution of smartphone-based indoor localisation
solutions.},

for an area the size of a single-family house, with an accuracy around one meter and a high
sensitivity to even the slightest movement. The literature about device-free localisation
systems typically concentrates on improving sensitivity, accuracy and discriminating power,
without worrying too much about the number of involved radio devices. In this paper, for the
first time, we demonstrate that device-free localisation can work with reduced performance
with as low as four anchors in an environment composed by two wide rooms. Being able to use so
few anchors opens the possibility of several use cases where installing tens of devices is not

one of the main pillars for the development of context-aware applications. In this context,
comparing and testing indoor positioning system is a hot topic in the indoor localization
research community. In fact, after several years algorithms and methods have been developed
and matured, no general frameworks exist yet to reliably compare them. The scarcity of common
datasets for off-line test of emerging indoor positioning systems, together with the lack of
available frameworks for real-time comparison and evaluation of indoor localization solutions,
is one of the main barriers to their standardization. The lack of a common usable software
framework for implementing and testing new algorithms, on a fair basis, is an additional
barrier. In this work, we address this research challenge by proposing a free software
framework enabling the development of indoor localization applications on the Android
platform. It is composed of two applications: \textit{PrettyIndoor} is a positioning app,
\textit{FingerFood} is a fingerprint-building app. We show that the framework's modular
architecture can be exploited to easily develop many data fusion strategies, in order to
easily compare and improve indoor positioning systems.},

AALOA has already appropriate prominence and is linked to European strategies which can help
to group people and associations around different project results and to position them in the
right way and manner. On the other side AALOA is depending on the community and on the
projects it hosts. To demonstrate this ambition and to give a demonstration for other European

abstract = {RSS-based indoor localization systems are widely accepted in the literature as
one of the less invasive localization technique. In fact, this range-based approach does not
require any special hardware and is available in most standard wireless devices. Furthermore,
judicious use of RSS (Receive Signal Strength) has not a significant impact on local power
consumption, sensor size, and cost. In front of these interesting characteristics, the
performance of the RSS approach is worst with respect to some more invasive ad hoc hardware
range-based solutions (such as Angle of Arrival, Time of Arrival etc.). In this paper we
propose a localization method that leveraging the context information, such as the knowledge
of being in a given room, increases the localization accuracy of RSS-based
methods. Performance evaluation is done via real measurements in an office environment
composed of three adjacent rooms.},

theoretical procedure that aims to evaluate the maximum attainable performance of any real
methods using RSSI for localisation purpose. Our analysis we present is based on a fine grid
of RSSI values in a room, which are computed via ray-tracing, and a maximum-likelihood

abstract = {Indoor localisation using inexpensive, non-dedicated wireless devices has spun
great attention in the last years. We witness the ubiquitous presence of Wi-Fi access points
in offices and homes, soon followed by the increasing spread of low-power, low-cost wireless
nodes using the Bluetooth and, in perspective, ZigBee technologies. The presence of a
potentially high number of wireless transmitters in indoor spaces has pushed researchers to
investigate whether their built-in received signal strength indicator (RSSI) could be
exploited to gain information on the relative position of a receiver with respect to a number
of transmitters and, by knowing in advance the position of those transmitters, to pinpoint the
receiver's position. Even though RSSI meters are not built to this end, but rather to give
information to the higher communication protocol layers about the status of the communication
link, their usage is highly attractive, because the information they give is obtained almost
``for free''. As a consequence, many studies exist which, analytically, through simulations or
through real measurements, analyse how a receiver ({\em mobile}) can best use RSSI relative to
multiple wireless transmitters ({\em anchors}) to compute its position. In this paper we use
detailed ray-tracing simulation to investigate the ultimate performance of indoor, single-room
localisation using RSSI measurements in a specific case, and we comment on the results. This
study does not lend itself to practical implementation of a localisation method, but rather
provides insight into the limits of methods based on RSSI.},

abstract = {On-body wireless sensor networks (WSNs) are gaining an increasing interest in
medical, military as well as entertainment applications. Wireless transceiver modules placed
on the body and combined with actuators/sensors can communicate between them and with any
other node located in the surrounding environment, without any human body movement constraint
with respect to wired connections. A further application of the above on-body WSNs could be in
the framework of the human body posture and activity detection. Recognizing people’s
activities is a key issue in Assisted Living (AL) applications, where it can be required to
monitor and detect abnormalities for elderly care, or rate how a person performs routine
activities. As an example, in the medical field the patient recovery and rehabilitation can be
remotely monitored, controlled and recorded without the presence of a technician. Likewise, in
military applications the Soldier Assist System (SAS) that provides recognition of soldier
activities can be improved by body activity detection networks. In this context the authors
are involved in a research activity aimed at developing algorithms for body posture/activity
classification, which are based on RSS (Received Signal Strength) exploiting. Indeed, the RSS
indicator is already available in most of low cost transceiver modules designed for WSNs
(Smart Dust or Motes). If only a rough classification of body posture/activity is required,
additional devices, as for example gyroscopes or accelerometers, could be avoided. The
development of the system architecture (number of transceivers and their best placement on the
human body) requires accurate path loss models to characterize radio links between a set of
transceivers placed on the human body, for a number of body postures and movements. Therefore,
as a first step of the above mentioned algorithm development activity, on- body path loss
properties are being studied. Both numerical and experimental results will be presented in
this paper. The analysis of the path loss as a function of the distance between two on-body
antennas is performed at 2.4 GHz and results are shown for some radio links.},

abstract = {In network engineering as in other areas, sophisticated software tools have
been conceived to handle models of increasing complexity. These tools theoretically support a
great number of input cases. However, in practice, they are confronted to a limited set of
inputs, since too large efforts are required to configure each new input case. Similarly, only
a few quantitative metrics are extracted from tool results, whereas the output files could be
analyzed in many different ways. The potential of a given tool could thus be decoupled if
these preprocessing and post-processing tasks would be wisely automated. In this paper, we
focus on these preprocessing and postprocessing operations, and propose a generic execution
environment which automates them. This environment permits in particular to assess the
influence of various parameters on the final results, and to perform generalized what-if
analysis.},

of them is based on field trials at the frame level. We present a series of measurements for
relating transmission distance and packet loss on a Wi-Fi network in rural areas and propose a
model that relates distance with packet loss probability. We show that a simple double
regression propagation model like the one used in the ns-2 simulator can miss important
transmission impairments that are apparent even at short transmitter-receiver
distances. Measurements also show that packet loss at the frame level is a Bernoullian process
for time spans of few seconds. We relate the packet loss probability to the received signal
level using standard models for additive white Gaussian noise channels. The resulting model is
much more similar to the measured channels than the simple models where all packets are
received when the distance is below a given threshold and all are lost when the threshold is
exceeded.},

investigate mechanisms that guarantee a certain level of Quality of Service (QoS) to the end

generic bandwidth-on-demand allocation in TDMA satellite systems; the patch is available as
free software. This simulator has been validated through experimental tests performed on the
Skyplex satellite system. Specifically, we run CBR UDP flows to measure the characteristics of
the satellite link in terms of throughput and delay and to verify that the simulative model
output matches the experimental dynamic throughput and one-way delay behaviour. The
simulations and experiments show that bandwidth-on-demand allocation mechanisms may cause
large delays when sudden variations in the incoming traffic rate occur, a behaviour typical of
multimedia flows.},

the overall channel efficiency is impaired by multiple effects, because of multipath fading in

issue by applying forward erasure correction codes (FZC) to MPEG-4 video sequences exchanged
by the hosts of a hybrid network, made of a satellite link and a wireless LAN using 802.11b
devices. A standard video streaming application runs on one end of the satellite link while,
at the final end, a wireless ad hoc network receives the multicast video stream. This work
aims at demonstrating the improvement in Quality of Service (QoS) of the video transmitted in
the hybrid network. The main parameters measured are the packet loss, the delivery delay, and
the overhead in bandwidth occupancy imposed by the use of FZC. The received video is then
evaluated by using a MOS (Mean Opinion Score) procedure.},

TCP performance is significantly impaired by the channel bit error rate. In this paper we
investigate the application of different FEC (forward error correction) types/rates and
different bit rates, for the optimization of TCP goodput, in transmissions over a rain-faded
geostationary satellite channel, provided that the end-to-end protocols are left unaltered. We
compare physical-level FEC techniques, such as convolutional encoding/Viterbi decoding and
Reed Solomon, link-level erasure codes and their combinations, over a wide field of
signal-to-noise conditions of the satellite channel. The case of multiple connections per link
is also analyzed, in addition to that of a single connection per link. . In order to evaluate

abstract = {Few researchers have performed measurements of a Wi-Fi channel at the frame
level in order to understand performance issues by relating frame errors and signal
strength. This paper presents results relative to ad hoc measurements in a rural
environment. We show that a simple double regression propagation model like the one used in
the ns-2 simulator can miss important transmission impairments that are apparent even at short
transmitter-receiver distances. We propose a two-ray propagation model which improves on those
commonly used for simulation purposes. Frames were transmitted and received by using two cheap
laptops with standard Linux drivers. Measurements also show that packet loss at the frame
level is a Bernoullian process for time spans of few seconds, and that longer time spans
exhibit a more complex behaviour, meaning that the 2-state Markov-modulated process often used
in the literature is not a good match for rural areas.},

abstract = {Few researchers have undertaken the task of measuring the wireless channel at
the frame level to understand performance issues related to frame loss and signal
strength. This paper proposes a measurement procedure for terrestrial wireless networks based
on cheap hardware and custom software, and validates it through experiments on real-word
wireless environment. In order to validate the measurement procedure, we carry out a
comprehensive measurement campaign in a rural environment and we evaluate statistics about
frame loss and signal level in the IEEE 802.11b wireless channel. Frames are transmitted and
received by using two cheap laptops with standard Linux drivers and purposely written
software. A first validation step compares the behaviour of the received signal power level
with the two-ray propagation model. A subsequent step compares the observed frame loss with
the expected coding gain at various transmission rates. Graphs of the observed frame loss rate
at different transmission rates are provided for a rural environment, where the two-ray
propagation model is a good fit.},

title = {Goodput optimization of long-lived {TCP} connections in a faded satellite
channel},
institution = {CNR-ISTI},

number = {ISTI-2003-TR-69},
address = {via Moruzzi, 1},
month = jun,
note = {Extended version},
abstract = {The optimization of the end-to-end throughput of a TCP connection over
geostationary satellite links is a challenging research topic because the high delay-bandwidth
product, together with a non-negligible random loss of packets, are conditions which differ
considerably from the original environment for which TCP was originally designed. As a result,
TCP performance is significantly impaired by the channel bit error rate. In this paper we
investigate the application of different FEC (forward error correction) types/rates and
different bit rates, for the optimization of TCP goodput, in transmissions over a rain-faded
geostationary satellite channel, provided that the end-to-end protocols are left unaltered. We
compare physical-level FEC techniques, such as convolutional encoding/Viterbi decoding and
Reed Solomon, link-level erasure codes and their combinations, over a wide field of
signal-to-noise conditions of the satellite channel. The case of multiple connections per link
is also analyzed, in addition to that of a single connection per link. In order to evaluate
the throughput of a TCP long-lived connection we used a method that is midway between analysis
(fluid model) and simulation.},
