Cognitive radio technology has been developed in recent years to make efficient use of the wireless spectrum especially for opportunistic spectrum access. Cognitive radio technology enables the secondary (cognitive) users to use the unused licensed spectrum of the primary users. Medium Access Control (MAC) protocol plays a vital role in spectrum utilization, Primary User's (PU) interference management and secondary user's coordination in Cognitive Radio (CR) networks. Here, the authors propose a new MAC protocol where control transceiver attached with sensor improves the accuracy of spectrum sensing result as well as protects the primary user from interference.
