DGP application for support traffic information systems in indoor and outdoor environments

Abstract

V2V and V2I systems are networks in which vehicles and roadside units are nodes able to broadcast environmental conditions over large distances. Each vehicle has an on-board unit (OBU) which may have several kind of sensors (satellite-based positioning systems and positional sensors like digital compass, accelerometers and gyroscopes), may be connected to the car control unit, and has a long-range wireless module (able to transmit up to 1000 m away). We used DGP for determination of vehicles position in space using a simple algorithm. The resulting matrix is diagonal symmetric and it’s therefore possible to apply a DGP algorithm.
