Abstract :
Cooperative sensing yields a significant sensing performance improvement. In this paper, we propose an effective sensing algorithm in distributed situation that is considering inband and outband sensing using evolutionary game theory. We drive that the strategy group of secondary users converge to the ESS. Secondary users in ESS state are able to cooperatively sense the channels with optimized group size.
