Abstract :
Cognitive Radio (CR) technology has emerged as a way to improve the overall spectrum usage by exploiting spectrum opportunities in both licensed and unlicensed bands. The Medium Access Control (MAC) protocol in CR network should support interference control for Primary Users (PU) and collision avoidance amongst Secondary Users (SU). In this paper, we propose a scheduling scheme for CR MAC protocol to detect PU as fast as possible, and demonstrate performance of our scheme through a simulation.
