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 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 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 place our message
ferrying work in the larger context by describing a novel taxonomy
for mobile wireless networks, which admits various ranges of
disconnection and mobility.

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. He 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. He is 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.
