ECE Team Wins Best Paper Award at IEEE/ACM Conference


October 29, 2004

ECE graduate students Arjunan Rajeswaran and Gyouhwan Kim, and their advisor, Rohit Negi, Assistant Professor of ECE, won the Philips Best Student Paper Award at the Broadband Wireless Networking Symposium (BROADNETS 2004). The Institute of Electrical and Electronics Engineers (IEEE) and the Association for Computing Machinery (ACM) event took place in San Jose, California on October 25-29. Their paper is titled "A Scheduling Framework for UWB and Cellular Networks."

The team simulates solutions for scheduling on wireless networks, which use the new Ultra WideBand (UWB) technology, and on the more familiar cellular networks, tackling the persistent issues of bandwidth and power with a new twist.

"Scheduling the different users of a wireless network efficiently is a hard problem of significant theoretical and practical value. This research presents a general and flexible framework to describe the scheduling problem," Rajeswaran explains. "The flexibility of the scheme is demonstrated through the example of Ultra WideBand networks as well as traditional cellular networks."

Their research group solves problems in wireless networks through a cross-layer design approach. Negi tapped on this theoretical expertise as a member of the technical program committee for BROADNETS and as chair of the performance analysis section. He also co-authored another paper at the conference, "Effective Capacity-Based Quality of Service Measures for Wireless Networks," with his former student Dapeng Wu, who earned his Ph.D. in ECE in 2003 and is now an Assistant Professor at the University of Florida.

Corporate sponsors for the conference included Philips, Nortel Networks, and NEC. Student travel grants were provided by the National Science Foundation.

In this multi-cell scenario, transmitters were distributed in two cells to study the effect of bandwidth on the scheduling solution.
