Abstract:-Cognitive radio is an emerging technology that aims at utilizing the spectrum efficiently. Cognitive radio is an intelligent radio which has the ability to allocate the spectrum dynamically. Cognitive radio detects the unused spectrum holes (spectrum sensing), characterizes the available bands (spectrum decision), the coordination with other cognitive devices in the access phase (spectrum sharing), and the capability to handover towards other spectrum holes when licensed users if a better spectrum opportunity becomes available (spectrum mobility). In this paper, a game theoretic framework is proposed to evaluate Spectrum allocation functionalities in Cognitive Radio Networks. The secondary users are the players of the game and the spectrum selection process is done based on the game theoretic frame work. In this paper we proposed pure Nash and mixed Nash strategies and simulations are done in matlab. Numerical results are reported to assess the quality of the game equilibrium.
