This research project deals with effective communications systems for advanced vehicular on-board digital equipments in order to accomplish enhanced ad-hoc communications networks. These communications systems enable a number of new communications schemes, including ad-hoc inter-vehicle communications (IVC), vehicle-pedestrian communications (VPEC), flexible road-vehicle communications (RVC), and integrated communications with vehicles and conventional fixed broadband networks. The project settled 5 research targets to develop the objective systems. (1)To establish a unified packet data structure, (2)to find out new algorithms to organizing ad-hoc networks for IVC and VPEC, (3)to present a new media access control for CDMA systems, (4)to present new and effective retrieval/access methods for vehicular users to acquire information they need, and (5)to develop actual communications systems to combine the protocol presented above in order to experiment the systems and certificate the vali … More dity of them.The above 4 researchers carried out the research project for 2002 and 2003, and obtained the following results. On issue 1, they set the unified packet format and data structure. They also presented some mechanisms to select essential information from the received information and reconstruct a new packet by mixing own data. On issue 2, they presented new algorithms to deploy ad-hoc wireless networks for IVC and VPEC. They showed the performance of the algorithms by simulations and experiments with actual vehicles. They also showed the validity of the systems for preventing from traffic accidents. On issue 3, they presented new access control scheme to obtain high throughput and small power consumption. On issue 4, the researchers proposed very new concept named Contents-Oriented Communications(COC). COC enable for users to acquire real-time traffic information which the users themselves can not clearly recognized what, where and how the information is. Finally, the researchers combined the elemental control protocols into total communication systems, investigated the availability of the systems in the actual environment by experiments, and quantatively certificated the basic operation and behavior of the developed systems.

本研究项目旨在为先进的车载数字设备提供有效的通信系统，以实现增强的自组织通信网络。这些通信系统实现了许多新的通信方案，包括特别车辆间通信(IVC)、车辆-行人通信(VPEC)、灵活的道路-车辆通信(RVC)以及与车辆和传统固定宽带网络的集成通信。该项目确定了5个研究目标，建立了目标体系。(1)建立统一的分组数据结构；(2)研究新的组网算法；(3)为码分多址系统提出一种新的媒体接入控制；(4)为车载用户提供新的有效的检索/接入方法；(5)开发实际的通信系统，结合上述协议，对系统进行实验并验证VALI…上述4名研究人员在2002年和2003年开展了研究项目，并取得了以下成果。在问题1中，他们制定了统一的数据包格式和数据结构。他们还提出了一些机制，从接收的信息中选择必要的信息，并通过混合自己的数据来重建新的分组。在问题2上，他们提出了为IVC和VPEC部署自组织无线网络的新算法。他们通过仿真和实际车辆的实验展示了算法的性能。这也表明了该系统在预防交通事故方面的有效性。在问题3上，他们提出了新的访问控制方案，以获得高吞吐量和低功耗。在第四期上，研究人员提出了非常新的概念，称为面向内容的通信(COC)。COC使用户能够获得用户自己无法清楚识别的实时交通信息，这些信息是什么、在哪里以及如何识别的。最后，研究人员将基本控制协议组合到整个通信系统中，通过实验考察了系统在实际环境中的可用性，并定量验证了所开发系统的基本操作和行为。较少
