Impact of Increasing Nodes over Proactive & Reactive Routing Protocol in VANET using NS3

although inter-vehicle communications (IVC) technologies intend to improve driving safety and enable infotainment applications, empirical testing within large-scale deployments remains cost-prohibitive, thus highlighting the need for ac- curate simulation models. While using current models, simulation practitioners limit future extensions and produce in- consistent results by choosing different design assumptions, thus motivating the following research objective: the goal of this research is to assess VANET network effectiveness by highly parameterizing in simulation mobility, radio propagation, and MAC/ PHY models that realistically represent VANET scenarios. We develop a simulation script for ns-3 that we execute for several realistic VANET scenarios and compare routing throughput, end-to-end delay, and safety message packet delivery ratio (PDR) to assess routing protocol performance of AODV and DSDV. We �nd that by combining synthetic highway or realistic vehicular traces with parametric sensitivity, VANET network and routing protocol performance can be meaningfully assessed.
