Title: Talk by Giovanni Neglia on Distributed Sub-gradient Method for Delay
Tolerant Networks [
Distributed Sub-gradient Method for Delay Tolerant Networks
Friday October 29, 2010
Speaker: Giovanni Neglia
In this talk we consider that nodes in a Delay Tolerant Network (DTN) may
collaborate to minimize the sum of local objective functions, depending in
general on some parameters or actions of all the nodes in the network. If
the local objective functions are convex, one can adopt a recently proposed
computation framework that relies on local sub-gradient methods and
consensus algorithms to average each node's information. Existing
convergence results for this framework can be applied to DTNs only in the
case of synchronous node operation and simple memory-less mobility models.
We address both these issues. First, we prove convergence to the optimal
solution for a more general class of mobility processes. Second, we show
that, under asynchronous operation, a straightforward application of the
original method would lead to sub-optimal solutions and we propose some
modifications to solve this problem. As a particular case study, we show
how the framework can be applied to optimize the dissemination of dynamic
content in a DTN.
Since September 2008, Giovanni Neglia is a researcher (Chargée de
Recherche) at INRIA Sophia Antipolis Méditerranée. He received a master's
degree in electronic engineering and a Ph.D. degree in telecommunications
from the University of Palermo, Italy, in 2001 and 2005, respectively.
After having spent 9 months as a research scholar in the computer networks
group at University of Massachusetts, he became a postdoc at University of
Palermo, and since September 2006 he was also an external scientific
collaborator in Maestro team at INRIA. His research focuses on modeling and
performance evaluation of computer networks and proposals of new mechanisms
to improve their performance.
