Performance analysis of AODV-based VANETs in Guwahati city: a comparative study of propagation models

Abstract

As a part of technological advancement, vehicular communication plays a vital role in modern day of urbanisation. The performance of Vehicular Ad-hoc Network (VANET) mainly depends on routing protocols and propagation models. This study looks into how different propagation models affect VANET performance in real time environment. As vehicle environments are dynamic and demanding, selecting an accurate propagation model is essential to create reliable communication. In this work, performance of widely used propagation models, such as Free Space Propagation (FRIIS), ITU-R P.1411 Loss Model and Nakagami fading are assessed and contrasted in Adhoc On-Demand Vector (AODV) routing-based VANET, considering various real-time traffic scenarios of Guwahati city using SUMO and NS3 platform. The results show that ITU-R P.1411 propagation model gives better Average Throughput, End-to-End Delay, End-to-End Jitter Delay and MAC/PHY-Overhead, whereas FRIIS routing protocol gives better Packet Delivery Ratio of Basic Safety Messages, Average Routing Goodput and Packet Delivery Ratio.
