Abstract: MANET describes distributed, wireless, mobile and multi-hop networks that operate without the benefit of any existing infrastructure except for the nodes themselves. A MANET network cloud is composed of autonomous, potentially mobile and wireless nodes that may be connected at the edges to the fixed, wired internet. In this paper, we study different mobility models proposed in the recent research literature and their performance of routing protocols Bellman Ford, Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR) and Distance Routing Effect Algorithm for Mobility (DREAM) by varying no. of nodes and mobility in terms of three metrics viz. Packet Delivery Ratio (PDR), end to end delay, and Throughput The simulation is carried out on NS -3 Simulator. The effort allows a fair comparison of the capabilities and limitations of different types of mobility patterns and their suitability for contemporary MANET routing protocols. 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.
