An Analysis of Stable Mobility Model for TORA & OLSR Routing Protocols in MANET

Abstract

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. In this paper, we have evaluated the performance of two routing protocols Temporally
Ordered Routing Algorithm Protocol (TORA-Reactive Protocol) and Optimized Link State Routing Protocol (OLSR-Proactive Protocol) based
upon different Mobility Models to analyse a Stable Mobility Model for MANET Routing Protocol. For experimental purposes, we have
considered four mobility model scenarios: Random Waypoint, Reference Group Point Mobility, Freeway and Manhattan models. These four
Mobility Models are selected to represent the possibility of practical application in the future. Performance comparison has been conducted
across the varying Node Speed with fixed Network size. Experimental results illustrate that performance of the routing protocol varies across
different mobility models.
