Characterising the Performance of AODV for Various Mobility Scenarios

Abstract

Mobile ad-hoc network (MANET) is an infrastructure-less, rapidly deployable and self-organizing distributed network with mobile autonomous terminals. Due to these characteristics, MANETs have always been important for defence applications especially for countries like India having boundaries and regions with large geographical diversity. Mobility is one of the defining features of MANET and has a major impact on the performance of routing protocols. In the present work, the performance of the AODV routing protocol is characterised for various mobility scenarios including random movement-based, controlled movement-based and realistic mobility models. A rigorous mobility and scalability analysis of AODV has been presented in graphical form considering transmission delay, number of received packet, control overhead, normalized routing overhead, packet delivery ratio and throughput as the performance measure. Network Simulator 2.35 is chosen as the primary simulator along with BonnMotion as well as the MOVE tool, for the generation of various mobility scenarios.
