Performance study of AODV for Ad hoc wireless networks

Abstract

An ad hoc wireless network is a network composed of mobile communication devices, which is designed to provide communication capability to satisfy the need of a temporary nature in an infrastructure-less environment. A routing protocol is necessary in ad hoc networks to ensure effective communication among nodes. This thesis presents a simulation-based study on the performance evaluation of Ad hoc on-demand distance vector (AODV) routing protocol, by comparing with the other on-demand routing protocol of Dynamic Source Routing (DSR). An event advanced simulation program was developed in Java to simulate the ad hoc wireless network implementing the AODV protocol. The performance metrics evaluated were packet delivery fraction, average end-to-end delay of data packets. A discussion on the effect of different network parameters such as the number of nodes and sources, the mobility and speed of nodes in the network is also presented.
