Simulation and Analysis of Routing Protocols in MANETS for Different Network Sizes

Abstract

Efficient deployment of MANET (Mobile Ad hoc Networks) requires high engineering research to overcome many challenges. Routing in MANET is one of the challenging tasks due to its dynamic topology and lack of centralized infrastructure. The communication in ad hoc network is uncertain because established route could be broken anytime. In recent years, several routing protocols have been proposed for mobile ad hoc networks and prominent among them are DSDV, DSR and AODV. This paper is a comparative study of these routing protocols under different network size showing the simulation results using NS2. We have chosen four performance criteria i.e. average energy consumed, end to end delay, and throughput and packet delivery fraction to compare these protocols.
