Abstract

A Mobile Ad hoc Network (MANET) eliminates the complexity of an infrastructure configuration and allows wireless devices to communicate with each other independent of central infrastructure. It does not rely on a base station to coordinate the flow of messages to nodes in the network. A primary challenge for each device is to maintain the information to route traffic and data packets. Here, in our paper we analyze the performances of Destination Sequenced Distance Vector Routing (DSDV), Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Ad hoc On-demand Multi-path Distance Vector (AOMDV) protocols based on the Quality of Service metrics i.e., Packet Delivery Ratio, Packet Loss, Delay, Control Packet Overhead and Throughput using the Network Simulator (ns-2). In this paper we are presenting functionality, benefits, limitations and simulation results for the above mentioned routing protocols.
