To overcome system latency and network delay is essential for intervehicle communication (IVC) applications such as hazard\r\nalarming and cooperative driving. This paper proposes a low-cost embedded software system dedicated to such applications. It\r\nconsists of two basic component layers: an operating system, named HEROS (hybrid event-driven and real-time multitasking\r\noperating system), and a communication protocol, named CIVIC (Communication Inter V�´ehicule Intelligente et Coop�´erative).\r\nHEROS is originally designed for wireless sensor networks (WSNs). It contains a component-based resource-aware kernel and a\r\nlow-latency tuple-based communication system. Moreover, it provides a configurable event-driven and/or real-time multitasking\r\nmechanism for various embedded applications. The CIVIC is an autoconfiguration cooperative IVC protocol. It merges proactive\r\nand reactive approaches to speed up and optimize location-based routing discovery with high-mobility nodes. Currently, this\r\nembedded system has been implemented and tested. The experiment results show that the new embedded system has low system\r\nlatency and network delay under the principle of small resource consumption.
