Accident Avoidance and Privacy-Preserving in V2R Communication using Chord Algorithm

Road accidents are the main issue and it creates a huge loss. So it's the challenging one in VANET in real time applications [20]. Here Vehicular Ad-Hoc Networks (VANETs) uses moving cars as nodes and acts as a wireless router in a network [11, 19]. It can communicate by using either V2V (vehicle-to-vehicle) or V2R (vehicle-to-roadside). The problem faced in vehicle-to-vehicle communication cannot lead to malicious attacks and it's tough in computing real time road conditions. By overcoming this problem vehicle-to-roadside infrastructure is used [14, 18]. Our aim in this paper is to improve security, traffic throughput and reduces the traffic delay in a highly congested area [15, 16]. In this paper network checks each vehicle speed for avoid accident based on predecessor and successor vehicle's speed using chord algorithm. We also implementing priority based vehicle movement. Network gives high priority for emergency vehicles and medium priority for registered vehicles and low priority for unregistered vehicles [17]. By this we analyze the performance of priority based vehicle movement and verification of vehicle speed using chord algorithm in network simulator-2.
