Impact of Radio Propagation Models on the Performance of Routing Protocols in MANET

A mobile Ad Hoc network (MANET) is a network which consist number of nodes that can openly and dynamically self-organize into random and temporary network topology. They allow people and devices to communicate with each other without any pre-existing network. Every mobile node is moving freely with different speed in random direction. So there is no guaranteed path from one node to another node. In previous years, a lot of new routing protocol has been developed in order to increase the performance of Ad Hoc network. In this paper, we investigate the effect of two non-fading propagation models, two ray ground model and free space model, on the performance of the ad hoc routing protocol such as Ad-hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Location-aided routing (LAR1) in term of packet delivery ratio, loss packet percentage, average end to end delay, average throughput, and routing overhead.
