Game Theory Based Energy Efficient Routing in Cognitive Radio Wireless Sensor Networks

A routing protocol for Cognitive Radio Wireless Sensor Networks (CRWSN) has been proposed here. The protocol is hierarchical. Various clusters are formed in the network, and each cluster contains one major cluster head node and two minor cluster head nodes. The cluster head nodes are selected by exploiting evolutionary game theory. The unique routing structure proposed in this work supports mobility of the cognitive radio nodes and offers energy efficiency and higher throughput. Future scopes of the work are outlined.
