Abstract
This paper combines the link reliability and the shortest time delay and a joint strategy for cognitive route, the policy routing process combined with spectrum allocation, adopt cross-layer approach, in the process of routing implementation spectrum availability judgment and update, ensuring the continuity of the routing process, reduce the high rate of the circuit. In this method assumes that each cognitive are equipped with a radio transceiver; A wireless communication interface; Transceiver can correctly perceive available spectrum, and when the spectrum utilization changes, can adaptively adjust; Wireless communication will result in the creation of public control channel, used for the exchange of information, the simulation results demonstrate the superiority of the algorithm.
