Spectrum Sensing: To Cooperate or Not to Cooperate? [PDF]
EAI Endorsed Transactions on Wireless Spectrum, 2014 While it is well accepted that cooperative spectrum sensing will significantly improve the sensing performance, the necessity of cooperation is not sufficiently appreciated. In this paper, by analyzing the spectrum sensing problem from the system perspective, we show that without cooperation, the performance will suffer from a fundamental tradeoff ...

Defending Against Cooperative Attacks in Cooperative Spectrum Sensing [PDF]
IEEE Transactions on Wireless Communications, 2013 Accurate spectrum sensing is important in cognitive radio networks. False sensing results in either waste of spectrum or harmful interference to primary users. To improve accuracy, cooperative spectrum sensing, in which a set of secondary users cooperatively sense the presence of the primary user, has emerged.
