T01 - Tutorial Title: Peer-to-Peer Networks - Application and
Performance Issues
Presenter:
Kurt Tutschku, Assistant Professor, University of Wuerzburg,Germany
Abstract:
Peer-to-Peer (P2P) networks
and P2P content
distribution applications have become very popular
lately, as witnessed by the relentless spread of file sharing
applications like eDonkey and BitTorrent. Latest observations reveal
that P2P applications have even surpassed the World Wide Web (WWW)
in popularity, at least in terms of traffic volume in provider
networks. However, P2P is not only restricted to file-sharing. It
may also comprise the use of self-organizing
P2P mechanisms for network control.
The efficiency of such a mechanism was just recently
demonstrated in a way impressive by the P2P VoIP application Skype.
The
aim of this tutorial is to give an overview on P2P and to provide
insights into the performance and applicability of P2P mechanisms in
networks for content distribution and network control. Resource
locating via Chord, Kademlia and Mobile P2P file-sharing are
selected as examples for investigating carrier-gradeness of P2P.
The
tutorial will explain what is understood by P2P, how P2P networks
operate, and how efficient P2P systems are. Therefore, we will first
provide an overview of the landscape of P2P protocols and
applications, outline their aims and describes the basic
terminology. Then, we will discuss thoroughly and evaluate P2P
algorithms for the searching of content/ resources. After that, we
focus on P2P mechanisms for content distribution. We explain
selected algorithms and assess their performance. The tutorial is
concluded by a summary and an outlook on future developments.

T02 - Tutorial Title: The Connected Automobile
Presenter:
Dave Marples, Chief Scientist Telcordia Technologies, USA.
Abstract:
This tutorial will review the current state, and future, of
networked automotive electronics; Starting with vehicles shipping
today before going on to consider the future of the Connected
Automobile and the advantages such connectivity could bring in a
long term architecture where most vehicles are capable of offboard
communication. The tutorial is split into two parts. In the first
part an overview of the current and emerging commercial landscape
for connected vehicles is presented, considering some of the
initiatives underway in Europe, the US and elsewhere with specific
attention given to the European GST and CVIS projects and the US VII
initiative. The technology, potential benefits to end users and
forecast timescales for adoption are all discussed. We review both
the private automobile and commercial vehicle value propositions
with their differing financial underpinnings. The tutorial will also
discuss the potential for new and novel services that are enabled by
such network connectivity.
In the second part, the engineering issues associated with the
development of the connected automobile are considered. Starting
with the sources of data in the vehicle and moving on through the
transmission, backhaul, storage and processing infrastructure needed
to support vehicle applications each of the stages of the flow if
data is considered in the light of the commercial initiatives
described in part one. These engineering issues are cross-referenced
back to the commercial initiatives considered earlier.
The tutorial is suitable for anyone with an interest in the future
of the connected vehicle and the changes that connectivity will
bring. Although there will be some technical material covered a deep
technical background is not a prerequisite for attendance and the
overall tutorial is suitable for anyone with a reasonably logical
mind.

T05 -
Tutorial Title:
Power Line Communications
Presenter:
Dr. Stefano Galli, Senior Scientist at Telcordia Technologies
Abstract: Home
networking transcends simple data or Internet access sharing among
multiple PCs so that today much attention is devoted to those
technologies that will enable multimedia support within the home.
Today, however, technology is not mature enough to provide
ubiquitous wireless home-networking solutions with truly multimedia
capability at a mass market price. Thus, it is reasonable to assume
that both wired and wireless solutions will coexist for some time
and will take care of different sets of applications. Among the
several wired alternatives,
home
networks based on PLCs promise a truly ubiquitous networking
solution. Therefore, the topic of PLCs is very relevant to the
consumer electronics industry.
The
goal of the proposed tutorial is to give a good understanding of the
main issues related to power line communications (PLCs). The
tutorial will start by reviewing the major applications of PLCs
(access, in-home, in-vehicle, smart grid, etc.), and pointing out
world trends and market status. Moreover, a brief overview of
standardization and PLC industry associations will be given. The
course will continue addressing the existing channel models, with
particular reference to recent results. Finally, the suitability of
modulation and coding techniques for the power line channel will be
reviewed.
The topic of PLCs is a very interdisciplinary one so it is
impossible to give an in-depth course on it in a half-day tutorial.
The course, however, will give a rather complete overview of the
major issues related to PLCs.

T06 - Tutorial Title: Autonomic
Wireless Networks in Smart
Environments
Presenter:
Antonio A. F. Loureiro, Department of Computer Science, Federal
University of Minas Gerais, Brazil
Linnyer B. Ruiz, Department of Electrical Engineering, Federal
University of Minas Gerais, Brazil
Abstract:
Autonomic Computing defines computational systems that are able
to manage themselves with none or minimal human intervention. The
implementation of the concepts related to autonomic computing in
computer networks leads to the development of a new concept:
autonomic networks. This kind of network is able to perform self
management of its elements and data communication links. The goal is
to have network services and functions performed without the
involvement of a human manager and in a transparent way to its
users. Besides, the network should be able to learn from the actions
performed by its elements and the analysis of all acquired results.
The automatic execution of tasks and the learning possibility
characterize the autonomic aspect of this kind of network.
Smart
environments represent the next evolutionary development step in
building, utilities, industrial, home, shipboard, and transportation
systems automation. In those scenarios, wireless transmission is
complex and often problematic, where a number of conditions such as
multipath interference, transmission collisions, and obstructions
adversely impact the reliability, scalability and data throughput of
high bandwidth communications. In addition, the vast majority of
applications and services for those scenarios were initially
designed to run on wired networks, and thus require considerable
technology adaptation for wireless implementation. Furthermore, in
order to ensure widespread adoption, the wireless modules deployed
must fit into the cost constraints of their environments. To cope
with those design challenges, in the future, we can expect to have
those networks to work in an autonomic way.
