摘要：Vehicles connected to each other through an ad-hoc system form a wireless network called vehicular adhocnetwork (VANET).VANET is a special kind of communication network which transfers data from vehicle toinfrastructure (V2I) as well as vehicle to vehicle (V2V).In VANET, Road Side unit (RSU) acts as wireless LAN accesspoint and it provide communication with infrastructure. In the existing system RSU act as server which transfer thepacket to the vehicles through an antenna. Vehicular Backbone Network (VBN) is the network in which the vehiclesare 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 asRelay 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 transmittedto 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 betweenvehicle and RSU is increased as well as packet drops are reduced.
