Vehicle-to-vehicle message transmission under VRP using SUMO and NS3 in an industrial area: a Pakistani case study

Metropolitan cities worldwide are subject to heavy traffic, which causes inconvenience and road jams, which can also hinder business activities. Vehicular ad hoc networks (VANETs) can help avoid such inconveniences and jams by providing an automated communication architecture among vehicles roaming in the city and surrounding areas. This study examines the two- propagation loss model such as Friis and two-ray propagation loss model for inter-vehicle communication for Sialkot, which is the biggest business hub of Pakistan. We selected OpenStreetMap to import the map of Sialkot's industrial area. Then, we used SUMO to convert the map into a map.xml file, and after that, the map.xml file was converted into mobility.tcl for NS3 to perform experiments. The overall research finds that propagation loss models (PLM) affect the performance of VANETs routing protocols (VRP) during message transmission. The evaluation suggests using the Friis propagation model to gain better performance and less physical overhead.
