Novel Relay Scheme Based on Traffic Type in Vehicular Networks

Emergency message propagated in vehicular networks is delay intolerance and crucial for safety management. While the non-real-time traffic can highly improves the quality and comfortable of everyday. However, due to the limited transmission coverage and the poor quality of time-varying wireless environment, the two type traffic need relay to assist in the completion of communication. So this paper is dedicated to present novel relay scheme for the transmission of the two type traffic. We propose an effective broadcast scheme (PCC) which adopts primary and candidate relaypsilas cooperative work for emergency message propagation. Also we present a novel relay scheme (RCS) in which relay vehicle is replaced by relay cluster for the transmission of non-real-time traffic. Simulation results help to prove that our schemes gain better performance.
