Collaborative Research: NeTS-NBD: Exploring the Design and Implementation of Vehicular Networked Systems

本研究从系统角度探讨车际网路。该构想是由智能车辆通过混合无线网络交换安全驾驶、交通状况监测、紧急信息传播、动态路线规划等数据组成的智能交通系统。该项目的主要目标是设计和实现一个灵活高效的车载计算平台，自下而上，从车载PC开始，直到服务和应用程序。该项目将研究与工程相结合，开发能够加速从被动事故避免向主动事故避免转变的车载软件，对交通安全产生重大影响。为了弥合研究和实际应用之间的差距，这个项目的重点是原型设计，以及在真实道路条件下的测试和评估。为了使这项研究的影响最大化并允许技术转让，与主要汽车制造商的研究实验室建立了持续的联系。该项目将产生一个车载网络协议栈，由四个特定于车辆的层组成：(i)数据验证和缓存，（ii）存储和转发消息路由，（iii）网络内处理，以及（iv）支持发布-订阅和移动查询的应用层。该网络堆栈将在车载计算平台上进行原型设计，该平台由车载pc、GPS接收器、IEEE 802.11或DSRC以及GPRS/3G通信链路组成，这些将在实验室中组装。将在此平台上开发和评估多个流量查询服务应用程序。本研究也将发展交通模型的研究和车辆网路系统的评估方法。

This research is exploring inter-vehicular networking from a systems perspective. The vision is an intelligent transportation system composed of smart vehicles exchanging data for safe driving, traffic condition monitoring, emergency message dissemination, and dynamic route planning over hybrid wireless networks. The main objective of this project is to design and implement a flexible and efficient vehicular computing platform, bottom-up, starting from a car PC, up to services and applications. This project combines research with engineering to produce vehicular software that can accelerate the transition from passive to active accident avoidance, with major impact on traffic safety. To bridge the gap between research studies and real-life applications, the focus of this project is on prototyping, along with testing and evaluation on real road conditions. To maximize the impact of this research and allow technology transfers, continuous contacts with research labs of major car manufacturers are established.This project will produce a vehicular network protocol stack, consisting of four vehicle-specific layers: (i) Data Validation and Caching, (ii) Store and Forward Message Routing, (iii) In-Network Processing, and (iv) Application Layer with support for publish-subscribe and mobile queries. This network stack will be prototyped on a vehicular computing platform, consisting of a car-PC, GPS receiver, IEEE 802.11 or DSRC, and GPRS/3G communication links, which will be assembled in the lab. Several traffic querying service applications will be developed and evaluated over this platform. This research will also develop a study of traffic modeling and an evaluation methodology for vehicular networking systems.
