A comparative study on AODV, DSR and DSDV routing protocols for Intelligent Transportation System (ITS) in metro cities for road traffic safety using VANET route traffic analysis (VRTA)

Road traffic safety can be improved and better and able to accomplish Inter-Vehicle Communications by implementing emergent cellular technologies such as Vehicular Ad-hoc Networks (VANET). VANET's are based on the hybrid network architecture, application scenarios of change of position that does not entail a change and location of a node. The principle imposed on the design of the routing protocol in the main dispute of VANET's. Intelligent Transportation System (ITS) acts as a solution for the above said. The study of Ad-Hoc On-demand Distance Vector Routing (AODV), Destination Sequenced Distance Vector (DSDV) and Dynamic Source Routing (DSR) has been done in this paper. The routing algorithms are used to moderate the accuracy based upon urban environmental characteristics like data drop, data collide, density of vehicle, end to end delay and throughput.
