Keynote
Message Ferrying and Other Short Stories:
Mobility-Assisted Data Delivery in Wireless Networks
Mostafa Ammar, Georgia Tech., USA
Abstract:
Disruption tolerant networks (DTNs) are a class of emerging mobile and
wireless networks that experience frequent and long-duration partitions.
These networks have a variety of applications in situations that include
communication in natural disaster areas or other hostile environments, deep-space
communication, vehicular communication, and non-interactive Internet
access in remote areas.
In this talk, I will first overview the basic motivation and
survey of some initial work in this emerging area. I will then provide an overview
of our work which is concerned with the development of a "Message Ferrying" (MF)
scheme, inspired by its real life analog, that implements a non-traditional
"store, carry and forward" routing paradigm using node mobility to
overcome network partitioning. In the MF scheme, a set of mobile nodes called
message ferries takes responsibility for carrying messages between disconnected
nodes. I will then summarize our recent work on providing a formal understanding
of the entire space of wireless and mobile networks. This effort provides a formalism
for classifying such networks and a framework that unifies DTNs with more traditional
MANETs.

Mostafa Ammar is a Regents' Professor with the College of Computing at
Georgia Tech. He has been with Georgia Tech since 1985. He received the
S.B. and S.M. degrees from the Massachusetts Institute of Technology in
1978 and 1980, respectively and the Ph.D. in Electrical Engineering from
the University of Waterloo, Ontario, Canada in 1985.
Dr. Ammar's research interests are in network architectures, protocols
and services. He has contributions in the areas of multicast
communication and services, multimedia streaming, content distribution
networks, network simulation and most recently in disruption-tolerant
networks and overlay network design.
Dr. Ammar has published extensively in these areas and was the
co-recipient of the Best Paper Awards at the 7th WWW conference and the
2002 Parallel and Distributed Simulation (PADS) conference. To date, 25
PhD students have completed their degrees under his supervision. He
served as the Editor-in-Chief of the IEEE/ACM Transactions on Networking
from 1999 to 2003. Most recently he was the co-TPC Chair for Co-Next 2006 and
ACM SIGMETRICS 2007. Dr. Ammar is a Fellow of the IEEE and a Fellow of the ACM.
