Cognitive radio is a promising technology aiming to solve the spectrum scarcity problem by allocating the spectrum dynamically to unlicensed users. It uses the free spectrum bands which are not being used by the licensed users without causing interference to the incumbent transmission. Cognitive radio networks are vulnerable to selfish attacks, where secondary users increase their accessing probability to enhance their own utilities, resulting in serious performance degradation in CR networks. The proposed work identifies a new selfish attack channel pre-occupation selfish attack in cognitive radio networks.
