Simulation study of Mobile Ad-hoc Networks routing protocols

Abstract

A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried out without any centralized control. MANET is a self organized and self configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. Routing is a critical issue in MANET and hence the focus of this paper along with the performance analysis of routing protocols. We compared four routing protocols i.e. AODV, DSR ,OLSR and ZRP. Our simulation tool will be Network Simulator (NS-2.34). The performance of these routing protocols is analyzed by two metrics: packet delivery fraction and End to end delay. All the four routing protocols are explained in a deep way with metrics. The comparison analysis will be carrying out about these protocols and in the last the conclusion will be presented, that which routing protocol is the best one for mobile ad hoc networks.
