Game Theory for Security in Cognitive Radio Networks

Cognitive Radio Networks (CRNs) appear as a probable solution for the shortage of spectrum. However, the Security in cognitive radio network becomes a challenging issue, since more chances are given to attackers by cognitive radio technology compared to general wireless network. These chances may cause degradation the network quality of service but currently there are no specific secure protocols for cognitive radio networks. By this motivation, we present the state of art in security of cognitive radio network. In addition, we present the existing game theory models and non-game theory model for security issues in CRN. The attacks in different protocols layers were also investigated.
