本文概述了高速公路协同防撞 (CCA)，这是一种新兴的车辆安全应用，使用 IEEE 和 ASTM 采用的专用短程通信 (DSRC) 标准。除了 DSRC 架构的描述之外，我们还介绍了 CCA 的概念及其在车对车无线网络环境中的实现要求，主要是在媒体访问控制 (MAC) 和路由层。然后概述了传统移动自组织网络的 MAC 和路由协议并不直接适用于 CCA 和类似的安全关键型应用。然后确定用于支持 DSRC 环境中此类应用的数据包路由协议的具体约束和未来研究方向。为了进一步解释 CCA 与其底层网络协议之间的相互作用，我们通过模拟车辆碰撞实验展示了 CCA 安全性能的示例。这些实验的结果还用于证明 CCA 等安全关键应用程序对网络数据优先级的需求。最后，根据实验结果讨论了CCA对不可靠无线信道的性能敏感性。
This article presents an overview of highway cooperative collision avoidance (CCA), which is an emerging vehicular safety application using the IEEE- and ASTM-adopted Dedicated Short Range Communication (DSRC) standard. Along with a description of the DSRC architecture, we introduce the concept of CCA and its implementation requirements in the context of a vehicle-to-vehicle wireless network, primarily at the Medium Access Control (MAC) and the routing layer. An overview is then provided to establish that the MAC and routing protocols from traditional Mobile Ad Hoc networks are not directly applicable for CCA and similar safety-critical applications. Specific constraints and future research directions are then identified for packet routing protocols used to support such applications in the DSRC environment. In order to further explain the interactions between CCA and its underlying networking protocols, we present an example of the safety performance of CCA using simulated vehicle crash experiments. The results from these experiments are also used to demonstrate the need for network data prioritization for safety-critical applications such as CCA. Finally, the performance sensitivity of CCA to unreliable wireless channels is discussed based on the experimental results.
