Spectrum sensing is the key constituent in Cognitive Radio (CR) networks for detecting the primary users. Due to the destructive circumstances of sensing channel such as multipath fading and shadowing, local sensing is not appropriate for the requirements for consistent detection. Consequently, cooperative spectrum sensing is acquainting with to perceive the primary user more precisely. Clustering methodology is considered as an effectual method that is used in cooperative spectrum sensing to confrontation the degradation in the performance of spectrum sensing due to fading and shadowing of reporting channel and also to lessen the control channel overhead when the numeral of cooperative users becomes very large.
