Building Robust Mobile Ad-Hoc Networks
Department of Computer Sciences, University of Texas at Austin
In this talk, I will discuss two issues in improving the robustness of mobile
ad-hoc networks: how to improve transport protocol performance given the
frequent and rapid topology changes, and how to protect the network when such
changes open new vulnerabilities.
While TCP is designed to adapt to a wide range of network characteristics and
traffic conditions, its performance still suffers under ad-hoc networks when
mobility induces sudden and drastic changes in route and path characteristics.
We have developed a set of techniques to address this problem, including
explicit bandwidth notification, and out-of-order detection and response.
Mobility also introduces security hazards in a mobile ad-hoc network. We have
aimed to apply intrusion detection techniques as a second wall of defense
(after failure of traditional prevention mechanisms), and have evaluated a key
mechanism, anomaly detection, for ad-hoc routing protocols through simulation
study.
Hosted by Alexander Wolf.
Refreshments will be served immediately following the talk in ECOT 831.
