Reputation-Based Consensus Cooperative sensing In Distributed Cognitive Radio Networks

摘要：

In cognitive radio (CR) networks, Cooperative Spectrum-Sensing can effectively resolve hidden primary user problem. In the exiting schemes, a consensus-based cooperative scheme has been promised, but the cooperative scheme has a weak robustness when there are misbehaved cognitive radios in the networks. So we propose a reputation-based scheme to classify the cooperative sensing nodes for successful consensus cooperation. This scheme can mitigate the harmful effect coming from the misbehaved nodes and sufficiently utilize the information of the behaved nodes, The simulation shows that the robustness of consensus cooperative sensing is significantly increased, and the performance of the sensing is also unproved.
