WIRELESS MOBILE AD HOC NETWORK BY USING DYNAMIC SOURCE ROUTING PROTOCOL

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any pre-existing network infrastructure or centralized administration. Routing protocols used in ad hoc networks must automatically adjust to environments that can vary between the extremes of high mobility with low bandwidth, and low mobility with high bandwidth. I have analyzed a routing protocol called Dynamic Source Routing (DSR). As a result of its unique design, the protocol adapts quickly to routing changes when node movement is frequent, yet requires little or no overhead during periods in which nodes move less frequently. By presenting a detailed analysis of DSR’s behaviour in a variety of situations, this paper generalizes the lessons learned from DSR so that they can be applied to the many other new routing protocols that have adopted the basic DSR framework. In the DSR protocol, a backup route will be initiated to transfer data (in route cache) when the initial route is broken. However, a backup route affects the overall network performance such as end-to-end delay, etc. In this paper, I showed the simulation results of the dynamic source routing protocol based on it’s throughput, pause time, packet received, drop packet ratio, end to end delay, packet delivery fraction, and routing overhead. This results shows that dynamic source routing protocol is an efficient protocol to be used in Ad Hoc network and its performance is good when its pause time is increases.
