talk title: Wireless Networks Capacity Characterization and How to Approach it
Prof. Leandros Tassiulas,
Computer Engineering and Telecommunications Dept., University of Thessaly, Volos, Greece
Abstract:
Wireless systems posses attributes fairly different than those formed the
design guidelines of the Internet. Hence novel approaches are needed for
architecting networks that seamlessly integrate wired and wireless
components and offer the grade of service people are accustomed from the
internet. In this talk we will review a number of theoretical advances
towards characterizing the capacity of wireless networks and present an
optimization based framework for developing algorithms towards achieving
that capacity. The necessary interaction among the different network layers
for realizing those resource allocation algorithms will be discussed while
implementation challenges both in terms of computational complexity as well
as state information availability will be presented. Implications on the
scaling properties of those algorithms and the associated network capacity
will be given. In the last part of the talk we will present attributes of
prevailing wireless network standards that support the incorporation of
optimization based resource allocation algorithms in practical network
designs and discuss current approaches.

Keynote
title: Multi-hop Ad Hoc Networking: from Theory to Reality
Prof. Marco Conti,
PerLab, Institute for Informatics and Telematics (IIT) National Research Council (CNR), Pisa, Italy
Abstract:
We discuss ten years of research about multi-hop ad hoc networking. We try to summarize the main achievements and to point
out the limits behind Mobile Ad hoc NETworks (MANET) research. This research has been carried out under the assumption that
these networks are mainly used for large-scale general consumer applications, and nodes are ubiquitous, thus reasonably dense
and active. Both assumptions are considerably far from reality and would certainly not be true in an initial phase of deployment.
Lack of realism in MANET objectives coupled with a lack of realism during MANET design are the main causes that are running MANET
towards a high risk of failing. Then we show that, while pure general-purpose MANETs do not yet happen in the real world, the
multi-hop ad hoc networking paradigm has been successfully applied in several classes of networks that are penetrating the mass
market. We take as examples mesh and opportunistic networks together with vehicular and sensor networks, where the multi-hop ad
hoc paradigm is applied in a pragmatic way to extend the Internet, and/or to support well-defined application requirements.
We oppose these successful areas of ad hoc networking to the lack of impacts of pure general-purpose MANETs, evidencing how
a more pragmatic approach is winner.

Keynote
title: Dynamic Mobility Management
Prof. Albert Y. Zomaya,
School of Information Technologies, The University of Sidney, Sydney, Australia
Abstract:
Location management strategies can be categorized into two main
groups: offline (static) and online (dynamic) schemes. In offline schemes,
the network has a unique behavior for all users, such as the current GSM
networks. On the other hand, in online schemes, different network
topologies are considered for different users. These topologies are
closely related to the movement pattern and calling behavior of each
user. Because online schemes are much more complex than offline ones, they
require more network computation capabilities. Thus, offline schemes are
more widely implemented. However, these schemes must use minimal network
resources to manage user tracking, and should not require massive
computation.
Traditional location management techniques for mobile networks are very
conservative and there is a need for more .intelligent. techniques. to
enable future networks to better predict the location of users in the
network based on their past movement history. Such strategies usually have
two different stages: modeling the users. behavior patterns and invoking
an intelligent algorithm to use the extracted model in order to locate the
users. Several algorithms and strategies have been suggested to solve the
stated problem in different ways. The use of Markov models is one of the
most popular techniques used for solving this problem. Other techniques
include can be classified as: history based, distance based, movement
based, and time based.
This talk will address the dynamic mobility management problem and will
suggest few computationally effective solutions that provide reasonable
accurate results.
