MAC Algorithm for Cognitive Radio Networks Based on Traffic Type

Ashwini S [20] | Manjul Krishna Gupta


Abstract: The radio spectrum is a scarce resource. Cognitive radio enables secondary users to access the portions of the spectrum that are not currently used by the primary users. Coordination is a central issue in cognitive radio networks whenever users share resources. There may be collision, congestion or interference, with loss of performance in a absent coordination. For this previously a protocol is proposed that enable secondary users to learn and teach with the goal of coordinating to achieve a round-robin Time Division Multiple Access (RRTDMA) schedule. But the problem in this solution is no consideration is given for type of traffic and urgency of traffic like voice and video. All the traffic is seen in the same level so the secondary users with higher priority traffic are not satisfied by this protocol. This paper proposes a priority based round-robin Time Division Multiple Access (PRRTDMA) schedule protocol that improves the throughput of the secondary users with higher priority traffic. The protocol is completely distributed, fast, efficient and scalable.
