Mobile ad-hoc network has no infrastructure, it is decentralized in nature and self configuring. MANET is dynamic that is each node can freely in any direction. Hence the main challenge in the MANET is to equip each device to maintain the information to equip the traffic. This paper evaluates analyze and compare various routing protocols in MANET like AODV, AOMDV, DSR, DSD. The simulation is carried out in ns2.35 under Unix platform. The performance metrics used for evaluation are packets delivery ratio, throughput and end-to-end delay. Keywords- AODV, DSDV, DSR, AOMDV, MANET, NS2.
