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.
