Ad hoc networks are autonomous, self-organizing systems of
(mobile) hosts and routers connected by wireless links and
forming an arbitrary graph with varying topology. Examples
include city-wide communication networks, satellites in orbit,
radio-linked sensors distributed randomly like seed by air-drop,
vehicle mounted devices, and unmanned emergency reconnaissance
platforms operating either standalone or connected to the Internet.
As such wireless systems are increasingly penetrating our critical
communication infrastructure and it is an ongoing challenge to keep
electronic data transmissions stable, efficient and secure.
This
session will address fundamental communication and security issues
in ad hoc networks.
