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.

Applications:

We are investigating vedio compression techniques in a wireless ad hoc environment. Specifically, we are interested in scalable compression techniques that involve matching the coding to to human perception and using adaptive transmission protocols.

Adaptive techniques are being examined and developed for Deployable Autonomous Distributed System (DADS). In particular, we are investigating issues relating to adaptive medium access control, routing, network management, and network security in an underwater acoustic environment.
