N2 - A group of connected and autonomous vehicles (CAVs) with common interests can drive in a cooperative manner, namely cooperative driving, which has been verified to significantly improve road safety, traffic efficiency and environmental sustainability. A more general scenario that various types of cooperative driving applications such as truck platooning and vehicle clustering, will coexist on roads in the foreseeable future. To support such multiple cooperative drivings, it is critical to design an efficient message dissemination scheduling in a shared communication channel. Most ongoing research suggests using the time-division multiple access (TDMA) method on top of IEEE 802.11p as a potential remedy. However, TDMA requires time synchronization and is not flexible, especially in the multiple cooperative drivings scenario where the beacon frequency needs to be updated and the number of cooperative drivings changes to meet the time-varying traffic conditions. In this paper, we focus on the study of the message dissemination protocol for platooning, a typical and well-known cooperative driving pattern. Specifically, we proposed a hybrid message dissemination protocol which aims at guaranteeing the reliable delivery of beacon messages for a multi-platooning system. We first adopt a TDMA-based medium access method for intra-platoon communication to improve the reliability and efficiency of beacon dissemination. We then present a token-passing medium access method for inter-platoon communication, which maps platoons into a token ring to schedule their beacon transmission time. We conduct extensive numerical experiments to validate the effectiveness of our protocol.
