Cognitive radio (CR) is an intelligent radio, which has been targeted to exploit the utmost available spectrum holes for unlicensed users by sensing the environment. A selfish cognitive radio node can occupy all or part of the resources of multiple channels, prohibiting other cognitive radio nodes from accessing these resources. Selfish cognitive radio attacks deals with serious security problem like fake signal attack, Channel pre-occupation attack. These security problems they significantly degrade the performance of a cognitive radio network. The proposed work provides selfish cognitive radio attack detection technique, called UJCSST, which will detect the attacks of selfish Secondary Users by the cooperation of other legitimate neighboring SUs. The UJCSST algorithm makes use of the autonomous decision capability of an ad-hoc communication network based on exchanged channel allocation information among neighboring SUs. This technique is simple and reliable and can be well fitted for practical work in future work.
