HOBOKEN, N.J. — A paper co-authored by Stevens Institute of Technology Professor Rajarathnam Chandramouli for the IEEE GLOBECOM 2008 Conference, titled "A game theoretic framework for distributed self-coexistence among IEEE 802.22 networks," is one of 11 papers selected to receive a GLOBECOM '08 Best Paper Award. GLOBECOM is IEEE Communication Society's flagship conference. Last year President Bush extended his personal congratulations to GLOBECOM on its 50th anniversary and Washington-area officials declared the week of November 26 "IEEE Global Communications Week."

Out of more than 1,000 papers accepted to be presented at GLOBECOM '08, 24 outstanding papers were nominated as candidates, and 11 that address different aspects of communications and networking were finally chosen to receive awards; this represents 1 percent of the papers selected for presentation at IEEE GLOBECOM 2008 Conference, to be held in New Orleans, November 30-December 4.

Each author of a winning paper will receive a certificate to mark this distinction during the Conference Banquet on Tuesday, December 2.

Professor Chandramouli's co-authors include Shamik Sengupta, a post-doctoral researcher in Stevens' Department of Electrical and Computer Engineering; and S. Brahma and M. Chatterjee of the Department of Electrical Engineering and Computer Science at the University of Central Florida in Orlando.

The cognitive radio based IEEE 802.22 wireless regional area network (WRAN) is designed to operate in the under-utilized TV bands by detecting and avoiding primary TV transmission bands in a timely manner. Such networks, deployed by competing wireless service providers, would have to self-coexist by accessing different parts of the available spectrum in a distributed manner.

"Obviously," said Chandramouli, "the goal of every network is to acquire a clear spectrum chunk, free of interference from other IEEE 802.22 networks, so as to satisfy the QoS of the services delivered to the end-users. In this paper, we study the distributed WRAN self-coexistence problem from a minority game theoretic perspective. We model the spectrum band switching game where the networks try to minimize their cost in finding a clear band. We drive a mixed strategy that the competing networks must adhere to in order to achieve the Nash equilibrium."
