N2 - Performance of routing protocol at network layer in Cognitive Radio Adhoc Networks (CRAHNs) is mainly based on the probability of channel availability for application data transmission. To attain, end-to-end channel-route control messages should be disseminated in an efficient mechanism with minimal channel-route re-connection delays. In CRAHNs, end-to-end channel-route failures can be mainly due to spectrum handoff (dynamic primary user intervention), selfish node activity, CR node handoff and bandwidth degradation. In order to enhance the application throughput, it is pivotal to determine the exact channel-route failure and provide alternate end-to-end channel-route path. To achieve, this paper proposes a “channel-route failure based Cognitive-AODV routing protocol” with the modifications in channel-route-error (channel-RERR) to detect the exact channel-route failure and provide the best alternate end-to-end channel-route path in between source and destination. Experimental results reveal that the performance of proposed Cognitive AODV routing protocol with selfish node activity, spectrum handoff and node handover is outperformed when compared with the existing Cognitive AODV routing protocols.
