Poster: Reliability enhancement in V2V networks through vehicle-assisted relaying

Abstract

Enhanced communication reliability in vehicle-to-vehicle (V2V) networks is crucial in enabling safe, smooth, and economical traffic in intelligent transport systems (ITS) and is a precursor to a fully autonomous driving system. One particular scenario of interest is when the communication link is between two vehicles located across a corner at an intersection in an urban setting. In this scenario, the direct communication link is obstructed by an obstacle/building and is expected to be of low quality. We propose agile vehicle-assisted relaying in which the transmitting vehicle exploits the help of a nearby vehicle, often inside the intersection and can see both the transmitting and receiving vehicles, to convey its message to the receiving vehicle. We use simulation to study reliability performance of the proposed communication scheme and compare it to the traditional direct transmission communication. We show that the proposed vehicle-assisted scheme substantially improves reliability for communication between the considered transmitting and receiving vehicles compared to direct transmission.
