ABSTRACT
A MANET is a type of wireless network which does not require any predefined infrastructure to get established and is a collection of mobile nodes forming a network by their own. The performance of MANETS depends upon various factors such as- routing technique, size of network, density of network, power and bandwidth etc. Mobility model is a representation of reality of a scenario in which nodes may move in real environment. It provides an insight that how each node may move under given circumstances. The aim here is to study the impact of mobility models on the performance of routing protocols in mobile ad hoc networks. For analysis purpose we have chosen the AODV (ad-hoc on-demand distance vector routing protocol) and DSR (dynamic source routing protocol). The performance is evaluated and analyzed for two mobility models Random Waypoint and Manhattan Grid through simulation. We have designed another scenario named CSM (City Scenario Model) and analyzed it along with the aforementioned modes. The performance metrics like packet delivery ratio, average end-to-end delay, normalized routing load, and throughput are evaluated using network simulator NS2 with varying node density and varying maximum allowable velocity in the network.
