AB  - Emerging as a new communication paradigm, cooperative communication is attracting lot of attention among the researchers. In Cognitive Radio Ad Hoc Networks (CRAHN’s), the relay selection with user cooperation could be advantageous to both primary and secondary transmissions. This study deals with cooperative relay nodes that are very good in performance. In cooperative games, players collaborate with each other to jointly maximize the total utility of the game. In non-cooperative game, each player selfishly maximizes its own stationary utility function to reach the best response with Nash equilibrium strategies. The results reveal that the summation of node utilities in cooperation nodes is always greater than non-cooperative relay nodes and the relay node should be selected and configured according to the system requirements in order to improve the performance of cooperative cognitive radio ad hoc networks.
