Resorting to the requirement of cognitive radio network and spectrum monitoring in wide-band spectrum sensing, a framework of wireless sensor network for spectrum sensing is proposed. The framework includes clustered network structure, frequency division based cooperative sensing and cooperative sensing result processing scheme. Furthermore, the key technologies of the implementation of this framework are analyzed.
