Impact of Random, Uniform node placement and Grid environment on the Performance of Routing Protocols in MANET

Abstract

An ad-hoc network is frequently represented as a group of mobile platforms or nodes where each node can move freely and randomly without the benefit of any fixed infrastructure except for the nodes themselves. They are often autonomous, self-configuring, and adaptive. Each node in an ad hoc network is in charge of routing information between its neighbors, thus imparting to and holding connectivity of the network. MANET has to face many challenges in various aspects; one of the future challenges is terrain size and node placement. Here, performance of two popular protocols in MANET i.e. AODV and DSDV is evaluated under three different node placements namely Random, Uniform and Grid using GLOMOSIM simulator. The performance analysis is based on different values of Radio Range in network and different network metrics such as Packet Delivery Ratio (PDR) and Average Delay.
