AN EVALUATION OF IMPROVED CLUSTER-BASED ROUTING PROTOCOL IN ADHOC WIRELESS NETWORK

In this paper we presents a performance comparison of Dynamic Source Routing (DSR), Ad hoc On Demand Vector (AODV), Cluster Based Routing Protocol (CBRP) and Improved Cluster Based Routing Protocol (i-CBRP) routing protocols which builds upon a cluster based wireless network infrastructure. This evaluation is necessary due to unique enhancement made to traditional CBRP by way of implementing congestion control scheme as part of the structure establishing i-CBRP. First, we introduce the network infrastructure on which the routing protocols are to send packets. We simulates Mobile Ad-Hoc Network (MANET) network infrastructure using NS2 network simulator. DSR, AODV, CBRP and i-CBRP routing protocols are implemented to generate various simulation results. The results shows that i-CBRP performs better in terms of average packet delay, throughput, volume of traffic controls and average packet delivery ratio when compared with CBRP, while DSR performs better in terms of total volume of control traffic. AODV is the overall best in terms of average packet delay
