MANET is a Mobile Ad-hoc NETwork in which each node can communicate with another node without using any existing infrastructure. The performance of ad-hoc network depends on mobility. In this paper, the performance of different mobility models random walk, random waypoint, RPGM, Manhattan grid, Gauss Markov is compared with routing protocols such as Ad-hoc On-demand Distance Vector (AODV), Distance Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), Ad-hoc On-demand Multipath Distance Vector routing (AOMDV). Simulation has been carried out using Network Simulator NS2.34 and its associated tools. Simulation results include comparative analysis of routing protocol vs. mobility models.
