Abstract :
In the distributed cognitive radio networks, users possess the ability to detect spectrum holes to communicate with others which make the traditional routing protocol ineffective. The fundamental challenges here are the interruptions which occur when primary users emerge and how to exchange messages to maintain the route in this situation. To deal with the problem, we propose a novel on-demand routing protocol, which takes into account a spectrum selection control and channel allocation to alleviate the impact caused by the primary users. Simulation results indicate that our approach is effective in maintaining the existing route.
