论文摘要
近年来，基于车辆临时网络（VANET）的连接车辆进步在智能运输系统（ITS）方面已在有效地传播信息方面引起了人们的重大关注。 Vanet使用专用的短距离通信（DSRC）来传播车辆之间和基础设施之间的消息。尽管基于DSRC的通信是可行的，但是当车辆不在彼此的传输范围内时，及时传播消息仍然具有挑战性。此外，当车辆密度在道路上增加时，DSRC通信渠道非常拥挤。为了解决这些限制，采用了两个新兴范式：1）车辆云计算和2）采用车辆雾计算来在连接的车辆环境中传播车辆之间的消息。车辆雾计算使用雾节传播车辆之间的消息。通过获取诸如1）网络连接，2）计算和3）存储的属性来形成任何现实世界对象。在本书章节中，我们根据DSRC，Vehicular Cloud Computing和Vehicular Fog Computing等技术来强调连接车辆中消息传播的重要性。我们的目标是帮助读者更好地了解互联车辆和通信技术的基本面，同时在车辆之间和基础设施之间传播信息。
Advances in connected vehicles based on Vehicular Ad-hoc Networks (VANETs) in recent years have gained significant attention in Intelligent Transport Systems (ITS) in terms of disseminating messages in an efficient manner. VANET uses Dedicated Short Range Communication (DSRC) for disseminating messages between vehicles and between infrastructures. Though DSRC based communications are viable, it is still challenging to disseminate messages in a timely manner when vehicles are not in the transmission range of each other. Furthermore, DSRC communication channels are heavily congested when the vehicle density increases on the road. To address these limitations, two emerging paradigms: 1) vehicular cloud computing and 2) vehicular fog computing are been adopted to disseminate message between the vehicles in a connected vehicular environment. Vehicular fog computing uses fog nodes for the dissemination of messages among vehicles. Any real-world object can be formed as a fog node by acquiring the properties such as 1) network connectivity, 2) computation, and 3) storage. In this book chapter, we highlight the significance of message dissemination in connected vehicles based on techniques like DSRC, vehicular cloud computing, and vehicular fog computing. Our objective is to help the readers better understand the fundamentals of connected vehicles and communication techniques while disseminating messages between vehicles and between infrastructures.
