Performance Evaluation of MANET Routing Protocol for Varying Number of Nodes

Ad hoc network is a network formed without any central administration which consists of nodes that use a wireless interface to send packet data. Since the nodes in a network of this kind can serve as routers and hosts, they can forward packets on behalf of other nodes and run user applications. The ease of deployment and the infrastructureless nature of Mobile Ad hoc Networks (MANETs) make them highly desirable for present communication technology. MANET is probably the most well-known example of this networking paradigm being developed around for over twenty years. Furthermore, the multi-hop ad hoc networking paradigm is often used for building sensor networks to study, control, and monitor events and phenomena. Though there has been considerable research in this area. In this paper, we are analyzing the performance of AODV, DSR and DSDV routing protocol based on throughput of receiving packets and Average End-to-End Delay via increasing number of nodes and observing its effect on Quality of Service (QoS) of Mobile Adhoc Network. For our simulation we had used a discrete event simulator known as NS2 .
