Project Objectives
The project focuses on fundamental technologies needed
to implement self-configuring surveillance networks. The semi-automonous
networks are usually comprised of several low-cost sensor
devices working together in chaotic, dangerous environments.
Our primary goals are to model the interactive dynamics of
surveillance networks and develop techniques for achieving
network adaptation to sensed changes in operational and environmental
conditions. In this context, the research thrust at University
of Wisconsin will focus on issues related to wireless network
management in these systems. The project is funded by United
States Army Research Office.

Project Objectives
The primary goal of the project is to address the challenges
of next generation mobile wireless communication through an
integrated approach involving antennas, receiver structures,
and network design. Specifically, the project proposes to
develop techniques for managing and exploiting the complex
and time varying nature of a wireless communication channel,
while meeting the power and bandwidth constraints of mobiles,
base stations, and networks. The project emphasizes integration
of digital receivers for multiaccess communication with smart
antennas and dynamic resource allocation.
Three key issues to be addressed in this project are:
- Design of high frequency, high bandwidth radiating and
receiving antenna which is agile in space, time, and polarization
- Design of multiaccess receivers which exploit available
modes of diversity
- Dynamic resource allocation of channel and network resources
for meeting the quality of service of ongoing communications
Another key element of this project is the integration of
student and faculty research activities at three universities:
Univesity of Wisconsin-Madison, University of Colarado-Boulder,
and Eurecom in France.
