چکیده
In Mobile Cognitive Radio Ad Hoc Networks routing is one of the most important issues to be addressed and desires deep investigation. In this paper, we propose a distributed and efficient cluster based interference aware routing protocol. It incorporates the spectrum availability cost and interference metrics into the routing algorithm to find better routes. A route preservation method is also incorporated in the proposed algorithm to repair the route when it is defective due to primary user activity. Results of ns2 simulations illustrate that, the proposed algorithm can well fit into the mobile cognitive radio ad hoc networks and improve the network performance. The results indicate that The UNITED provides better adaptability to the environment and increases throughput and reduces data delivery latency.
