In this paper, a Cognitive Radio based Medium Access Control (CR-MAC) protocol for wireless sensor networks that utilizes cognitive radio transmission is used. In cognitive radio (CR) networks, identifying the available spectrum resource through spectrum sensing, deciding on the optimal sensing and transmission times, and coordinating with the other users for spectrum access are the important functions of the medium access control (MAC) protocols. In this paper, the sensor nodes are classifieddoi:10.9790/1676-0350105 fatcat:pfyv3ft2y5dtzcsiebfywnijtm
