A mobilead hoc Network (MANET) is an infrastructure less, decentralized multi-hop network where the mobile nodes are free to move randomly, these making the network topology dynamic. MANET routing protocols show different performance in different mobile network scenarios. In this paper an attempt has been made to understand the characteristics/behavior of ad hoc on demand distance vector (AODV) and Fisheye State Routing (FSR)protocols. The analysis of these protocols has been done using NS-2.
