摘要：

We propose a cooperative multiband spectrum sensing scheme for a cognitive radio network operating in the presence of malicious users. More precisely, we investigate the optimality of cooperative spectrum sensing with the aim of optimizing the detection performance and then maximize the aggregate achievable throughput given a bound on the aggregate interference imposed on the primary network. Comparative simulation results validate the superiority of our proposed method in terms of detection accuracy compared to conventional defense techniques used to combat the presence of malicious attackers.
