Vehicular Ad Hoc Network Relay Node Backbone Scheme

Abstract

Vehicle ad hoc networking is a unique communication that communicates messages and alerts between vehicles and access points that provide rural, urban and highways. Such communications tie together all road networks by creating routes and communication system. It offers intelligent transportation, comfort, and security and infotainment applications. In VANET, the vehicles are the nodes, and it forms high mobility topology. Timely delivery of messages is the most vital aspect in vehicular networks to reduce roadside issues. So selecting the node for messaging transmission is a critical job for correct delivery. There are various ways for selecting, and this paper discusses relay node selection in which the vehicles are elected automatically as Relay nodes. It has many benefits in relay node selection as the packet delivery is high, the loss is low, and the end to end delay reduced. This paper examines the highway regime, and it chooses the freeway mobility model.
