SIMULATION-BASED PERFORMANCE ANALYSIS OF VANET ROUTING PROTOCOLS IN URBAN TRAFFIC ENVIRONMENTS USING SUMO AND NS3

Abstract

Vehicular Ad Hoc Networks (VANETs) represent an emerging subset of Mobile Ad Hoc Networks (MANETs) specifically applied within the traffic sector. VANETs are becoming a crucial component of intelligent transportation systems due to their capability to enhance road safety and facilitate efficient vehicle-to-vehicle (V2V) communication. This study uses Simulation of Urban Mobility (SUMO) and Network Simulator 3 (NS3) simulator to provide an extensive performance study of VANETs routing protocols. Three well-known routing protocols are the subject of this study: ad hoc on-demand distance vector (AODV), destination-sequenced distance vector (DSDV) and optimized link state routing (OLSR) in terms of two different Friis and Two Ray Ground (TRG) propagation loss model that are used to analyze these protocols. A thorough industrial estate map of the city Sialkot, Pakistan, is obtained from OpenStreetMap and utilized in the SUMO simulator to create vehicular traffic scenarios in order to replicate genuine traffic circumstances. The routing protocols performance evaluated using the NS3 simulator, taking into account important parameters including, packets received receive rate, overhead, packet delivery ratio, and goodput. The findings show that for every parameter examined, the OLSR technique performs better as compare to DSDV and AODV. In particular, with Friis propagation model it performs better in terms of goodput and packet delivery ratio. The research demonstrate how crucial propagation models are to the effectiveness of routing methods in VANETs. The research also offers useful advice on how to use routing protocols and propagation models strategically in order to maximize VANETs performance.
