广播传输是车辆间通信（IVC）中协作驾驶传播安全相关信息的有效方式。然而，它也面临着消息冗余、链路不可靠、隐藏终端、广播风暴等根本性挑战，极大地降低了网络性能。在本文中，我们介绍了一种跨层方法来设计一种高效可靠的广播协议，用于 IVC 系统中的紧急消息传播。我们首先通过共同考虑地理位置、物理层信道条件和车辆的移动速度，提出了一种用于中继选择的新型复合中继度量。基于中继度量，提出了分布式中继选择方案，以确保选择唯一的中继以在期望的传播方向上可靠地转发紧急消息。我们进一步应用 IEEE 802.11e 增强型分布式协调访问 (EDCA) 介质访问控制 (MAC) 来保证安全相关服务的服务质量 (QoS) 供应。此外，还开发了一个分析模型来研究所提出的跨层广播协议（CLBP）在中继选择延迟和紧急消息访问延迟方面的性能。给出网络模拟器（NS-2）的模拟结果来验证我们的分析。结果表明，CLBP不仅可以最小化广播消息冗余，而且可以在IVC中快速可靠地传递紧急消息。
Broadcast transmission is an effective way to disseminate safety-related information for cooperative driving in intervehicle communication (IVC). However, it is fraught with fundamental challenges such as message redundancy, link unreliability, hidden terminals, and broadcast storms, which greatly degrade network performance. In this paper, we introduce a cross-layer approach to design an efficient and reliable broadcast protocol for emergency message dissemination in IVC systems. We first propose a novel composite relaying metric for relay selection by jointly considering geographical locations, physical-layer channel conditions, and moving velocities of vehicles. Based on the relaying metric, a distributed relay-selection scheme is proposed to assure that a unique relay is selected to reliably forward the emergency message in the desired propagation direction. We further apply IEEE 802.11e enhanced distributed coordination access (EDCA) medium-access control (MAC) to guarantee quality-of-service (QoS) provisioning to safety-related services. In addition, an analytical model is developed to study the performance of the proposed cross-layer broadcast protocol (CLBP) in terms of the relay-selection delay and the emergency message access delay. Network Simulator (NS-2) simulation results are given to validate our analysis. It is shown that the CLBP not only can minimize the broadcast message redundancy but can quickly and reliably deliver emergency messages in IVC as well.
