Performance Analysis of Ad Hoc on-Demand Distance Vector Routing Protocol for MANET

Abstract

The drastic increase in the number of wireless devices and bandwidth requirements, most networks have evolved to distributed networks rather than central client-server configuration. In order to cater a larger number of devices, that is not centrally controlled, a routing scheme is needed that can work with limited configured devices, supports fully dynamic and distributed configurations, and does not overwhelm the network with control messages for the destination that exists in the network but has no message to send. Similarly, this work is focusing on performance analysis of Ad hoc on-demand Distance Vector (AODV) routing protocol to create a mobile ad hoc network (MANET) environment. The simulation has been designed for the real environment of NED University of Engineering and Technology, Karachi, Pakistan, where several buildings of various departments need to communicate with each other without compromising the node's performance with the change in the network occur. The simulation results show that the AODV provides better network performance with fewer packet drops and consistent throughput through the network for varying speeds and locations. The results proved that as compared to Destination-Sequenced Distance Vector (DSDV), the end-to-end delay had shown not much improvement, but comparative delays are observed.
