Study on Performance Analysis of MANET Routing Protocols using NS3

Abstract

A Mobile Ad-hoc Network (MANET) [1], sometimes called a mobile mesh network, is a self-configuring network of mobile devices connected by wireless links. In other words, a MANET is a collection of communication nodes that wish to communicate with each other. [2] Ad-hoc networks require no centralized administration or fixed network infrastructure such as base stations or access points and can be quickly and inexpensively setup as needed. A MANET is an autonomous group of mobile users that communicate over reasonably slow wireless links. The network topology vary rapidly and unpredictably over time because the nodes are mobile. MANET is kind of wireless Ad -hoc network, is a self-configuring network of mobile routers connected by wireless links the union of which forms an arbitrary topology. The earlier MANETs are called “Packet radio networks” and were sponsored by DARPA in the earlier 1970’s. [2] There are several ad hoc routing protocols that propose solutions for routing within a mobile ad hoc network. This paper compares common reactive and proactive routing protocols such as Ad hoc on-demand distance vector (AODV), Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR) and Destination-Sequenced Distance-Vector (DSDV) by using a simulation platform to evaluate the performances.
