Interpretation and Investigations of Topology based Routing Protocols applied in Dynamic System of VANET

Abstract

Abstract The intelligent transportation system is necessary for smart connection among vehicles and roadways equipment. VANET is an emerging research area and gaining attention for this smart connection where each vehicle is a node in the ad-hoc network consists of groups of stationary or moving vehicles. These dynamic system of vehicles are linked together through a wireless link i.e., VANET. It provides an infrastructure that builds new solution for safety, comfort of drivers and passengers but the implementation of the VANET presents a hurdle in the selection and designing of a routing mechanism for dynamic vehicle system which is capable of providing reliable and efficient transportation of packets. To improve performance of dynamic system of VANET there are several routing protocols which may enable packet transport from the source node to the destination node. The prior objective of this research is to select and suggest reliable routing protocol for VANET’s implementation in vehicle system dynamics. This research presents the overall investigation and interpretation of routing protocol based on topology i.e., AODV, OLSR, DSR, and DSDV on the grounds of simulation parameters (packet delivery ratio, overhead, throughput). The performance is evaluated using network simulator (NS-3) and mobility simulator (SUMO). The result shows that in case of throughput and overhead, protocol DSR outperforms but in case of PDR, protocol AODV outperforms. From the above, conclusion is that this research will assist the researchers in selecting the better routing protocol in the implementation of dynamic system of VANET infrastructure.
