无基础设施的车载自组织网络提供安全和非安全应用的潜力是相当显着的。城市、郊区和农村地区的VAN拓扑结构可以表现出完全连接、完全断开或稀疏连接的行为，这取决于一天中的时间或无线通信设备的市场渗透率。在这篇文章中，我们专注于高速公路的情况下，并提出了一种新的分布式车载多跳广播协议的设计和实现，可以在所有的交通状况，包括极端的情况下，如密集和稀疏的交通状况。DV-CAST是一种分布式广播协议，它仅依赖于本地拓扑信息来处理VAN中的广播消息。结果表明，所提出的DV-CAST协议在可靠性，效率和可扩展性方面的性能是优秀的。
The potential of infrastructureless vehicular ad hoc networks for providing safety and non-safety applications is quite significant. The topology of VANETs in urban, suburban, and rural areas can exhibit fully connected, fully disconnected, or sparsely connected behavior, depending on the time of day or the market penetration rate of wireless communication devices. In this article we focus on highway scenarios, and present the design and implementation of a new distributed vehicular multihop broadcast protocol, that can operate in all traffic regimes, including extreme scenarios such as dense and sparse traffic regimes. DV-CAST is a distributed broadcast protocol that relies only on local topology information for handling broadcast messages in VANETs. It is shown that the performance of the proposed DV-CAST protocol in terms of reliability, efficiency, and scalability is excellent.
