通过车辆自组织网络（VANET），车辆到万物（V2X）为交通路口附近的车辆网络物理系统（VCPS）中的协同驾驶提供信息通信。但由于VANET网络拓扑结构的快速变化和车辆间的高速或长距离，使得消息的传播往往是不可靠和缓慢的。为了实现车辆自组网中协同驾驶的可靠、快速的消息传播，本文提出了一种基于无缝连接的消息传播机制（SC-MPM），它是车辆自组网中的一种机会主义选择模式。所提出的机制可以在V2X通信中提供具有低延迟数据优化的基于无缝连接性的认证过程。实验分析表明，SC-MPM可以降低消息冗余，提高消息传播速度，增强不同业务密度下数据传输的可靠性和有效性。
Through Vehicular Ad-hoc Networks (VANET), Vehicle-to-Everything (V2X) contributes information communications for the cooperative driving in Vehicle Cyber Physical Systems (VCPS) at a traffic intersection vicinity. But the message propagation is often unreliable and slow due to the rapid change in network topologies and the high velocities or long distances among inter-vehicular in VANET. In order to achieve a reliable and fast message propagation for the cooperative driving in VANET, this study develops Seamless Connectivity-based Message Propagation Mechanism (SC-MPM), it is an opportunistic choice mode in VANET. This proposed mechanism can offer the seamless connectivity-based switchover procedure with a low-delay data optimization in V2X communications. The experimental analyses show that SC-MPM can recline message redundancy, increase message propagation velocity, and enhance data transmission reliability and validity in different traffic densities.
