Abstract
Today wireless networks are becoming popular because of their “3 Any's ”- Any person, Any where, Any time. Mobile ad-hoc networks (MANETs) is an emerging research area with practical application. Dynamic and reliable protocols are required in MANETs, as they have no infrastructure (base stations) and their Network topology changes frequently. There are different protocols for handling the routing problem in MANETs. In this paper we focused on the two popular algorithms Ad-hoc on Demand Distance Vector (AODV) and Dynamic Source Routing (DSR), both being reactive routing protocols. We analyze and compare their performance through simulation using NS2 simulator. We province Quality of Service (Qos) in aspects of packet delivery rate, average time delay and routing load overhead by varying network size and transmission range of the respective nodes. The general observation from the simulation is that for application oriented metrics such as average delay and packet delivery rate, DSR outperforms AODV in less dense situations. AODV, however, outperforms DSR in more dense situations. However, DSR consistently generates less routing load than AODV.
