This paper evaluates the performance of the ETSI Contention-Based Forwarding (CBF) GeoNetworking protocol for distributing warning messages in highway scenarios, including its interaction with the Decentralized Congestion Control (DCC) mechanism. Several shortcomings of the standard ETSI CBF algorithm are identified, and we propose different solutions to these problems, which are able to reduce the number of transmissions by an order of magnitude, while reducing the message end-to-end delay and providing a reliability close to 100% in a large area of interest.

ETSI ITS 基于竞争的转发 (CBF) 在高速公路场景中的警告消息的评估和改进

本文评估了 ETSI 基于竞争的转发 (CBF) 地理网络协议在高速公路场景中分发警告消息的性能，包括它与分散式拥塞控制 (DCC) 机制的交互。识别了标准 ETSI CBF 算法的几个缺点，我们针对这些问题提出了不同的解决方案，它们能够将传输次数减少一个数量级，同时减少消息端到端延迟并提供接近的可靠性在大面积感兴趣的区域中达到 100%。
