Vehicle Accident Prevention on Curve Roads using VANET

Abstract

Vehicular ad hoc network is infrastructure less networks, which have dynamic wireless nodes with the RSU. In real life vehicular communication, data broadcasting is a difficult task for the drivers. This difficulty leads to vehicle accidents on curve roads. Centrifugal force, fog, coverage of vehicle by another vehicle, curved nature of the roads and skill of the drivers are the main reason for vehicle accidents on the curve roads. Due to those factors, vehicle accidents being occurred on the curved nature of roads. Therefore, in this paper vehicle, accident prevention algorithm on the curve roads has been proposed using quantitative research methodology for vehicles to vehicle and vehicle to infrastructure communications. To prevent the accident on curve roads, we have used RSU on the curve roads to create communication with the OBU of the vehicles. For these, we have implemented and tested the proposed algorithm using a simulation tool called NS2.35 for V2V and V2I communication scenario and computed the performance of the algorithm on different parameters of the network. The simulation result of the proposed vehicle accident prevention algorithm on a curve road improved the packet delivery ratio, throughput, end-to-end delay and routing overhead by 11.91%, 4.7%, 11.4% and 1.5% from the previous value of 86.8%, 20.6%, 20.9%, and 22.2% respectively for different number of vehicles
