Relay node backbone scheme in vehicular adhoc network

Vehicular Ad hoc networking is a peculiar networking communication which transmits messages and warnings between vehicles and access points which incorporates rural, urban and highways. These communications bring all the road side systems to work together by establishing routes and communication links. It offers intelligent transportation, comfort, 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 road side issues. So selecting the node for messaging transmission is a critical job for correct delivery. There are variant ways for selecting and this paper discuss about 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, loss is low and end to end delay is reduced. This paper examines the highway regime and it chooses the freeway mobility model.
