A Proposed Algorithm to Enhance Security in CRN

With the growing demand of the wireless spectrum leading to its scarcity, motivated the use of Cognitive Radio as the successful way to deal with this problem. The efficient exploitation of the spectrum is done by the Cognitive Radio that allows the licensed spectrum to be utilized by the unlicensed users effectively. This paper illustrates an algorithm which enhances the security in CRN irrespective of the security threat or the attack done by the malicious users. It uses the concept of cluster head generated through random numbers and the formation of slots for the free spectrum based on the round robin algorithm. The efficient management of the spectrum is done so that each user utilizes the spectrum in an effective way without causing harm to the primary users.
