Vullikanti Wins NSF CAREER Award

Publish Date: 12/30/2008

Anil Vullikanti, a joint appointment with the Department of Computer Science and the Virginia Bioinformatics Institute (VBI), has received the National Science Foundation's (NSF) prestigious CAREER award for this proposal entitled  "Cross-layer optimization in Cognitive Radio Networks in the Physical interference model based on SINR constraints: Algorithmic Foundations." This award is being funded by the Network Technology and Systems program within the Computer and Networked Systems division of NSF. Dr. Vullikanti's award brings to 12 the total number of early-career awards won by CS faculty from NSF or DOE.

The goal of Dr. Vullikanti's proposal is to examine the theoretical foundations of cognitive radio networks(CRN), which increase the spectrum utilization by opportunistically, allowing unlicensed users to transmit on licensed bands without causing unacceptable interference for the licensed users. This proposal studies cross-layer optimization problems in such networks using a more realistic model of interference. The results of this proposal will contribute to the theoretical underpinnings of the broader area of wireless networks, not just the application of CRN, because of the central role 
interference plays.

Dr. Vullikanti is part of the Network Dynamics and Simulation Science Laboratory in VBI.
