Power Control Algorithm Based on Game Theory in Cognitive Radio Networks

The basic principle of cognitive radio technology and knowledge of game theory are introduced briefly. The characteristic of non-cooperative power control game algorithm is analyzed. A power control game algorithm base on game is raised according to the characteristic and request of the cognitive radio system. Users are allowed to improve the performance of a certain in both the transmission power and the revenue than the non-cooperative power control game algorithm,the simulation result shows our algorithm has better performance in utilization and fairness of power control.
