The existence of malevolent interferences and intrusions in the Cognitive Radio networks will dramatically deteriorate the efficiency of spectrum sensing. Throughout this paper, the changes in the cooperative spectrum sensing network model have been proposed .In this paper we have modified the cooperative spectrum sensing model to analyse malevolent interferences, where a fusion centre is transmitted the local signal to noise and disruption power ratios for making appropriate decisions. Performance analysis has been done in terms of various variables i.e. false alarm and detection chance. Simulation findings are given to validate the theoretical analysis.
