Cognitive Radio provides enhanced wireless communication performance through context-aware sensing and adaptation. Cooperative relay enhances network connection quality and improved system throughput. Applying cooperative relay communication technique on Cognitive Radio networks enables Cognitive Radio to opportunistically exploit cooperation between network nodes. This integrated design that benefits from both cognitive network operation and cooperative communications. One of the key challenges in the Cognitive Radio based cooperative relay network is to seek optimized network node cooperation in a distributed environment. Recently, game theory has been applied to solve communications and networking problems. In this paper, we adopt a game theoretic approach to facilitate the cooperative relay in Cognitive Radio networks.
