In order to achieve cooperative driving in vehicular ad hoc networks (VANET), broadcast transmission is usually used for disseminating safety-related information among vehicles. Nevertheless, broadcast over multihop wireless networks poses many challenges due to link unreliability, hidden terminal, message redundancy, and broadcast storm, etc., which greatly degrade the network performance. In this...
This paper proposes a multi-channel token ring protocol (MCTRP) for inter-vehicle communications (IVC). With MCTRP, the emergency messages can be quickly disseminated with bounded delay, and the desired quality-of-service (QoS) for multimedia traffic can be provided with limited hardware requirement and signaling cost. In addition, MCTRP ensures that all nodes have an equal opportunity to transmit...
