An Approach to Detection Probability of Cluster-Based CRN

The performance of cognitive radio network (CRN) is directly linked with presence of primary user. The major challenges of cognitive radio networks (CRN) are sensing of primary user by secondary user and cooperation among secondary user. The sensing of primary user can be controlled through spectrum sensing capabilities of secondary user while cooperation between secondary user become more complex with increasing secondary user in CRN. In this paper we have study existing method for sensing primary user by secondary user. Combine cluster based network and energy detection sensing method proposed that improves cooperation among secondary user and inherently reduces overhead. The result shows reduction in access time and increase the probability detection for CRN.
