| Abstract: | A game theoretic solution for distributed dynamic frequency selection and power control policy in cognitive radio networks was proposed.Cognitive users could be coordinated by cooperation to improve the performance of distributed decision algorithm.Simulation results carried on a module based general simulation platform show that the proposed scheme can converge to system stable status rapidly with low implementation flexibility. |
