Todays' spectrum environment faces so many challenges but the spectrum scarcity is one of the most critical problem. To solve this problem effectively, Cognitive radio is a perfect technology identifying the vacant portion of the spectrum and also ensuring that primary users are not affected at all. In sensor network it is reasonable to adopt cognitive radio capability, which ultimately yields a new sensor networking paradigm, i.e. cognitive radio wireless sensor network (CR-WSN). MAC protocols
