Mobile ad hoc network is a collection of dynamic node which temporary connect and leave the network at any time. In Manet, there is no centralized or router, each mobile node must act as router and host at the same time. Due to node high mobility, the topology between two end nodes changes frequently. This paper analysis the performance of routing protocols (AODV, SAODV, DSDV and AOMDV) for different scenarios using Network Simulator � 2 and provides the comparisons with different network parameter (Packet Delivery Fraction, End to End Delay, Throughput, Overhead and Energy) between them.
