In this paper, we study cooperative multi-channel spectrum sensing in cognitive radio networks (CRNs) with quality of service (QoS) requirements. We first formulate the statistical QoS guarantees in wireless communication in CRNs. Next, the theoretical results on the effective bandwidth to perform the evaluation of the transmission are presented. This paper also proposes a method for multimedia streaming with the required QoS constraints in CRNs. Finally, we consider the cooperative spectrum sensing method among secondary users (SUs) in the CRN with QoS requirements. The simulation results show that the use of cooperative spectrum sensing can improve the performance of SUs with multiuser diversity.
