Performance Evaluation of WCETT Routing protocol for CRAHN

-Cognitive Radio Networks (CRNs) are new technology that facilitates the opportunistic of using the frequency spectrum. The idea of CRN is permitted secondary user access to licensed spectrum, but without any interference with the primary user and this will lead to good usage of spectrum. Routing protocols used to address the best route choice between the sender and receiver in a Cognitive Radio Ad-Hoc Network (CRAHN) consume substantial amount of energy from the battery which considered one of the serious problems in CRAHN. So a lot of efforts have been spent on enhancing the protocols techniques to improve this valuable energy. WCETT routing protocol is one of the best protocol that used an effective route choice between sender and receiver with a lower cost than other on demand routing protocols in CRAHNS. This paper focuses on the performance evaluation of WCETT protocol in CRAHN based on different issues like number of nodes, traffic, and number of radio in each node using NS3 tool.
