Abstract

Cognitive radio is an emerging technology in wireless access, aimed at vastly improving the way radio spectrum is utilized. In this paper, we investigate the performance improvement gained by applying cognitive radio to a multiple Wireless Service Providers (WSPs). We consider several WSPs and two types of flows: classical (CL) and cognitive radio (CR) flows. We propose two admission control schemes for CR flows and we show the potential improvement that could be gained by utilizing cognitive radios in the presence of classical flows. We develop several performance metrics for CL and CR flows.
