On move dynamic location detection without GPS In vanets

Abstract

High density of vehicles made the possible threats and road accident increased. Wireless Technology aims to equip technology in vehicles to lessen these factors by sending beacons to each other. Vehicular ad hoc networks (VANET) enable vehicles to communicate amongst themselves i.e. Vehicle to Vehicle communication (V2V) and Vehicle to road-side infrastructure communications (V2I). VANETs help in making driving on roads a safe task by informing drivers about immediate environmental conditions, e.g. vehicle collisions, road blocks, traffic jams. In the project, autonomous information from stored digitized maps and from vehicle sensors is combined with information received via RF links from nearby vehicles and the infrastructure. A spatial database named local dynamic map is the project deliverable which reflects all relevant stationary, transitory and dynamic information in the noticeable range of a stationary object (road side unit) or moving object (vehicles and other road users).
