Security and Quality-of-Service in Mobile Ad Hoc Networks

About the series

Lecturer: Brian Mark, Assistant Professor at George Mason University

Fueled by the availability of low-power microprocessors and ubiquitous connectivity, communication networks are becoming increasingly wireless and mobile. As ubiquitous computing applications become more widespread, networks will be characterized by massive deployments of intelligent, often invisible devices that are mobile or embedded in an ad hoc wireless environment. Ad hoc wireless networks, also known as MANETs (mobile ad hoc networks), must be capable of supporting seamless anytime-anywhere access to communications and computing resources on a very large scale. Such networks, while extremely compelling for the user, pose profound problems of security and quality-of-service provisioning.

In this talk, we shall give an overview of MANETs and their security vulnerabilities, and explore the complex interactions among security, routing, and mobility management. We will then look at some recent research work on secure routing and mobility management for MANETs and motivate the need to consider security and quality-of-service in a unified framework. We will discuss our preliminary investigations into integrating security as one aspect of an overall quality-of-service framework for MANETs, which would enable protocols for security, routing, and mobility management to be tuned so as to realize various tradeoffs between security and quality-of-service performance.

About the Lecturer:
Brian L. Mark received his undergraduate education in Computer Engineering with an option in Mathematics in 1991 from the University of Waterloo in Canada and his Ph.D. in Electrical Engineering from Princeton University in New Jersey. He was a Research Staff Member at the NEC Research Laboratories in Princeton, New Jersey from 1995-1999. In 1999, he was on part-time leave from NEC as a visiting researcher at the Ecole Nationale Superieure des Telecommunications in Paris, France. In 2000, he joined the Department of Electrical and Computer Engineering at George Mason University in Fairfax, Virginia, where he is currently an Assistant Professor. His main research interests are in the areas of broadband multimedia networks, wireless communications and networking, and network security. He received an NSF CAREER Award in 2002.
