克服系统延迟和网络延迟是车辆间通信（IVC）应用（如危险报警和协同驾驶）的关键。本文提出了一种低成本的嵌入式软件系统专用于此类应用。它由两个基本组件层组成：一个操作系统，名为HEROS（混合事件驱动和实时多任务操作系统），和一个通信协议，名为CIVIC（通信车辆间智能等合作）。HEROS最初是为无线传感器网络（WSNs）设计的。它包含一个基于组件的资源感知内核和一个低延迟的基于元组的通信系统。此外，它还为各种嵌入式应用程序提供了可配置的事件驱动和/或实时多任务机制。CIVIC是一种自动配置的协作式IVC协议。它融合了主动和被动的方法，以加速和优化基于位置的路由发现与高移动性节点。目前，该嵌入式系统已经实现并进行了测试。实验结果表明，该嵌入式系统在资源消耗小的原则下，具有较低的系统延迟和网络延迟。
To overcome system latency and network delay is essential for intervehicle communication (IVC) applications such as hazard alarming and cooperative driving. This paper proposes a low-cost embedded software system dedicated to such applications. It consists of two basic component layers: an operating system, named HEROS (hybrid event-driven and real-time multitasking operating system), and a communication protocol, named CIVIC (Communication Inter Vehicule Intelligente et Cooperative). HEROS is originally designed for wireless sensor networks (WSNs). It contains a component-based resource-aware kernel and a low-latency tuple-based communication system. Moreover, it provides a configurable event-driven and/or real-time multitasking mechanism for various embedded applications. The CIVIC is an autoconfiguration cooperative IVC protocol. It merges proactive and reactive approaches to speed up and optimize location-based routing discovery with high-mobility nodes. Currently, this embedded system has been implemented and tested. The experiment results show that the new embedded system has low system latency and network delay under the principle of small resource consumption.
