A Cognitive Radio (CR) network is a wireless network in which smart devices can automatically detect available channels in the wireless spectrum called “White Spaces” and adapt transmission parameters optimizing the overall radio spectrum use. The efficiency of CR systems depends upon two major factors including quality of service and mobility management. In this project, a mobility scheme using the cooperative theory is presented to allow CR users to switch towards the best available spectrum band while changing the network. The proposed method establishes trading mechanisms between primary and CR users, which enables the latter to select the best band with a low price and large use duration. Simulation results prove that the proposed method conserves the frequency and the bandwidth required for various applications and ensures users’ continuity of service while moving from one network to another, which results in high utility for both primary and CR networks.
