可能需要车辆间通信系统在没有基站的情况下支持车辆网络的实时通信。基于这个前提下，本文提出了一种分布式MAC层协议，即筛除（ES-DCF）协议，它包含了显式的实时流量在ad-hoc无线网络中的支持设计。ES-DCF使用优先级冲突避免和确定性冲突解决机制，以便为不同类别的实时数据流量提供及时交付保证。进行的仿真研究证实，ES-DCF表现良好，在最大限度地减少硬实时数据包丢弃的数量。
Inter-vehicle communication systems may be required to support real-time communication for a network of vehicles in the absence of a base station. Based on this premise, the paper presents the design of a distributed MAC layer protocol, namely the elimination by sieving (ES-DCF) protocol, that incorporates explicit support for real-time traffic in an ad-hoc wireless network. ES-DCF uses the mechanisms of prioritized collision avoidance and deterministic collision resolution in order to provide timely delivery guarantees to different classes of real-time data traffic. The simulation studies performed confirmed that ES-DCF performs well in minimizing the number of hard-real time packets dropped.
