Channel and QoS Adaptive Multimedia Wireless Ad Hoc Networks
 
Topics:
Physical Layer Design
MAC and Data Link
Network Protocol Design
Applications
Simulation And Testbed
Research Focus And Objective:

The objective of this research is to develop an innovative framework, backed by theory and verified by software-hardware hybrid simulations, for the design of adaptive multimedia wireless networks. We focus our efforts on two critical areas that we believe hold the key to a new paradigm of network design:

(a) Theory and methodologies that facilitate cross-layer design of adaptive multimedia ad hoc networks;

(b) Software and hardware simulation platforms that verify design methodologies and predict, possibly in real-time, network behavior.

Network Protocol Design:

Incorporating channel and traffic information into routing protocols is one of focus areas. We are investigating several new concepts relating to adaptive multipath routing, QoS-based rounting, Ticket-based adaptive routing, and Multicasting. Research in middleware is directed toward integrated adaptation framework and network QoS mapping. Emphasis is also placed in security where we are interested in channel and QoS sensitive techniques.
