Cognitive Radio Routing and Optimal Spectrum Assignment Algorithm


Article Preview

Aiming to the shortcoming of traditional route protocols in cognitive radio networks, cognitive radio routing and optimal spectrum assignment (CRRSA) algorithm was proposed. In this paper, we consider the situation that non-interfering among the adjacent jump, and present the optimal allocation of available spectrum, and then calculate the bandwidth of end-to-end path, finally select the maximize bandwidth of end-to-end path as the best transmission route. Simulation results show that the End-to-End bandwidth of CRRSA is larger than that of traditional routing algorithm.
