Abstract: MANET stands for Mobile Ad hoc Network. An ad hoc network is often referred to as an “infrastructure less” network, because the network does not need fixed routers . These nodes are mobile communicating through wireless medium. Each ad hoc node may be capable of acting as a router. It’s characterized by multi-hop wireless connection and frequently changing networks. Due to frequent topology changes and routing overhead, selection of routing protocol in Mobile Ad-hoc Network (MANET) is a great challenge. A design issue for an efficient and effective routing protocol is to achieve optimum values of performance parameters under network scenarios. There are various routing protocols available for MANET. This paper involves study of four routing protocols (Bellman Ford Routing, FSR, CGSR and SHARP), and performance comparisons between these routing protocols on the basis of performance metrics (throughput, packet delivery ratio, and end to end delay measured after simulation of network) with the help of QualNeT Simulator. In this study we have considered three mobility scenarios: Random Waypoint, Group Mobility and Freeway Models. These three Mobility Models are selected to represent possibility of practical application in future.
