Cognitive Radio (CR) is a promising wireless technology which is helpful for the unlicensed users to utilize the free spectrum resources of licensed users. In cognitive radio ad-hoc networks, some nodes may be selfish nodes i.e. unlicensed users in order to occupy fully or partially available free spectrum resources. There has been done some research on selfish attack detection in CR networks. One of the selfish attacks is the channel pre-occupation selfish which broadcast the fake information among the Secondary Users (SUs). There may be a number of selfish nodes in this type of attack which significantly degrade the network performance.
