Due to continuously increasing demand of wireless communication technology, the problem of spectrum shortage arises. Cognitive radio technology enables efficient utilization of the existing wireless spectrum resources. CRN utilizes spectrum band by allowing secondary users to use the spectrum opportunistically, by changing their transmission parameters. We need to analyze the performance of a wireless network. To analyze the performance of a wireless network, game theory is used due to its ability to model individual, independent decision makers. In this paper we model how game theory can be used to allocate power levels to different CR nodes in a CRN at physical layer to ensure a certain QoS.
