Abstract:
In this paper, we analyze the effect of different degrees of node cooperation on the performance of routing protocols for cognitive radio networks. We first present an analytical model of the routing performance in terms of expected end-to-end packet delivery ratio (PDR) for cognitive radio networks with uncooperative node behaviors. We also performed extensive simulations to evaluate the analytical model. The simulation results show that Optimal Primary-Aware Route Quality Protocol (OPERA) could provide better PDR performance under higher degrees of network cooperation and Shortest Path First routing protocol (SPF) works better under lower cooperation degrees. Finally, our results suggest that even a modest level of node cooperation is sufficient to achieve significant performance improvement with respect to the fully non-cooperative network in which all secondary users are selfish.
