Performance Comparison and Evaluation of Proactive, Reactive and Hybrid Routing Protocols in MANET

Abstract

Mobile Ad-hoc Network (MANET) is self-organizing and self-configuring multihop wireless networks where the structure of the network changes dynamically. This is mainly due to the mobility of nodes. The nodes in the network not only act as hosts but also as routers that route data to or from other nodes in network. In mobile ad-hoc networks a routing procedure is always needed to find a path so as to forward the packets appropriately between the source and the destination. The main aim of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology and establish a correct and an efficient communication path between any two nodes with minimum routing overhead and bandwidth consumption. The design problem of such a routing protocol is not simple since an ad-hoc environment introduces new challenges that are not present in fixed networks. This paper evaluates the performance of various adhoc routing protocols such as DSDV, AODV, DSR, TORA and AOMDV in terms of energy efficiency and showed that AOMDV is better in comparison with all the above protocols. The simulation is carried out using network simulator NS-2.35 under Linux platform. The performance metrics used for evaluation are packet delivery ratio, throughput, and energy consumption.
