Abstract: In the cooperative spectrum sensing, if too many nodes take part in the cooperative data fusion, it would weigh the channel overhead and energy loss lot but improve the spectrum sensing performance little. This paper focuses on the channel overhead of cooperative spectrum sensing and the lifecycle of cognitive networks, and proposes a novel cooperative spectrum sensing algorithm. In the algorithm, all of the nodes are sorted by means of counting reliability. Only a part of nodes participate in the cooperative data fusion in the fusion centre. It cut down the number of nodes participating in the data fusion and save the average energy of the sensing nodes. The simulation results show that the proposed algorithm can effectively reduce channel overhead and prolong the lifecycle of cognitive network in the premise of ensuring the spectrum detection performance.
