Application of Game Models for Cognitive Radio Networks

Cognitive radio technology addresses the intelligent and adaptive models in wireless devices to obtain the unused spectrum (spectrum holes) without any inconvenience to the licensed users. Stochastic models were developed to detect and allocate the unused spectrum. Game theory models are the recent applications that support the latest future for efficient use of spectrum holes. The chapter discusses different game models and their applications to cognitive radio networks. The game theory models include potential games, cooperative games, and noncooperative games. The applications of game models require the mapping of cognitive components to game models. The application leads to efficient allocation of the unused spectrum to cognitive users. Further, the game models help to reduce the false alarms in detecting the primary user and communicate the cognitive users to track the available channels and obtain the appropriate channel.
