Data Broadcasting Using Backbone Driven Operation for Two Dimensional Highways in VANET
Vehicles connected to each other through an ad-hoc system form a wireless network called vehicular adhoc network (VANET).VANET is a special kind of communication network which transfers data from vehicle to infrastructure (V2I) as well as vehicle to vehicle (V2V).In VANET, Road Side unit (RSU) acts as wireless LAN access point and it provide communication with infrastructure. In the existing system RSU act as server which transfer the packet to the vehicles through an antenna. Vehicular Backbone Network (VBN) is the network in which the vehicles are self elected as Relay Node (RN) and RN forward the packet to neighboring vehicles in one dimensional highway. The proposed work enhance the throughput capacity for two dimensional highways, here vehicles are self elected as Relay node (RN) based on their location but RSU has two folds which will send and receive the packet from vehicles. Based on the dynamic formation of a multi-hop backbone network the event that has occurred in roads are transmitted to RSU. Vehicles are equipped with a sensor that detects the road accidents and informs to nearest RSU via the VBN. In enhanced VBN, the network is constructed along various directions according to road path. The throughput between vehicle and RSU is increased as well as packet drops are reduced.
