—We consider a wireless cognitive radio network in which a set of secondary users (SUs) opportunistically utilize the wireless spectrum licensed to the primary users (PUs) to tra...
—In this paper, a wireless cognitive radio sensor network is considered, where each sensor node is equipped with cognitive radio and the network is a multi-carrier system operati...
Abstract--Cognitive radios (CRs) are devices that access spectrum opportunistically taking advantage of unused portions of licensed spectrum. Therefore, depending on the licensed r...
