Position verification in vehicular communications
2013
In this paper, we propose a novel positioning methodology for a moving observer vehicle to estimate the location of a target vehicle without having to rely on fixed roadside infrastructure units (RSU) as reference nodes. It also enables the moving observer vehicle to verify the GPS assisted location claims by the target vehicle. The proposed method exploits the periodic retransmission of beacons as per the Dedicated Short Range Communication (DSRC) protocol that covers wireless communications for Vehicle-to-Vehicle (V2V) driver-assistance applications. We have conducted simulations and numerical analyses to evaluate the effectiveness of the proposed method.
