A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. Each node participating in the network acts both as host and a router and must therefore is willing to forward packets for other nodes. Research in this area is mostly simulation based; Random waypoint is the commonly used mobility model in these simulations. In this paper we have compared the performance of DSDV, AODV and DSR for different node speeds. Experiment results illustrate that performance of the routing protocol varies across mobility and node density.
