摘要：Now a day�s Wireless communication plays an important role in many of the user applications. Many of these applications follow either unicast or multicast routing protocol for their communication. In wireless mesh networks multicast routing protocol is mostly adopted as we can send more data packets to multiple places at the same time. So it is more important to understand and evaluate routing protocols in wireless mesh networks as it provides more reliability, efficiency with less bandwidth than in any other networks. In this paper we have simulated, examined and analysed two important routing protocols namely Primary user in cognitive radio network (PUCRN) and cluster based routing protocol in cognitive radio network (CBRP-CRN) which are models of mesh based routing protocols in wireless mesh networks. To better evaluate these routing protocols we have made required changes in the fields like change in number of nodes, pause time, traffic pattern and other parameters. We have used performance metrics like end to end delay, throughput and packet delivery ratio to evaluate the performance of PUCRN and CBRP-CRN in cognitive radio wireless mesh networks. Our scope of work will help you to compare and evaluate these two routing protocols using NS2.
