A COMPARATIVE ANALYSIS OF PROACTIVE ROUTING PROTOCOLS (DSDV, OLSR) & REACTIVE ROUTING PROTOCOLS (AODV, DSR) IN MANET USING NS-3

Abstract

The abstract outlines a comprehensive analysis focusing on routing protocols in Mobile Ad Hoc Networks (MANETs). Ad-hoc networks are dynamic wireless networks without a central infrastructure. This analysis compares two types of routing protocols—proactive (table-driven) and reactive (on-demand)—using simulation analysis. The protocols DSDV, OLSR, AODV, and DSR are evaluated using NS-3, considering various performance metrics under different scenarios. The research aims to provide insights into protocol strengths and weaknesses, aiding network protocol selection and potential enhancements. This investigation contributes to understanding routing behaviours in ever-changing MANETs, benefiting network design and optimization efforts.
