Development of Contents-Oriented Wireless Communications Networks for On-Board Information Facilities in Inter-Vehicle communications

本研究项目的目标是为没有任何基站和信息中心的车辆和移动用户开发近期类型的自组织网络技术。在近1公里×1公里平方的受限区域内，我们追求实现先进的自组织网络系统，使该区域的车辆、行人和PC移动用户能够紧密地相互通信，并获得一些实时的热点信息。我们提出了一种新的通信系统，称为面向内容的通信(COC)。在这个系统中，任何人都可以紧急地获取自己需要的信息，而不知道这些信息在哪里，或者是什么类型的信息和/或ID。本文的研究成果如下：1)通过获取车辆的位置信息并进行交互，开发了车辆避碰支持系统VACSS；2)开发了车辆行人通信系统VPEC，使一些小型行人终端能够与附近的车辆直接通信；3)利用COC.4开发了实时交通估计系统；开发了针对地震、火灾、恐怖爆炸、爆炸等重大事故的实时态势识别算法大屠杀、枪击等事件时有发生。我们称这种系统为紧急紧急通信。

The objective of this research project is to develop near-future typed adhoc networking technology for vehicles and mobile users without any base stations and information centers. In restricted area with almost 1 Km by 1 Km squared, we have pursued to realize advanced adhoc networking systems that enable vehicles, pedestrians, and PC mobile users in the area to communicate each other tightly and get some real-time hot information. We have proposed a new communications system named Contents-Oriented Communication (COC). In this system, any one can get their necessary information urgently whether they do not know where such information is or what kind information and/or ID the information is. We have developed the algorithms for that system, and verified the validity of the proposed systems by computer simulations and various experiments with three vehicles.As results of the researches we have had the following.1) We have developed VACSS (Vehicular Collision Avoidance Support System) by getting the location information of vehicles and exchanging those with each other.2) We have developed VPEC (Vehicle PEdestrian Communications) to enable some small pedestrian terminal to communicate with nearby vehicles directly.3) We have developed the real time traffic estimation system by using COC.4) We have developed the real time situation recognition algorithms when some tragic accidents like Earth-quake, Fires, Terrorist' bombing, Massacre shooting and so on happen. We call this kind of systems, EUC (Emergency Urgent Communications).
