Collaborative Research: NeTS-NBD: Exploring the design and implementation of vehicular networked systems

本研究从系统的角度探讨车联网。该愿景是一个智能交通系统，由智能车辆组成，通过混合无线网络交换安全驾驶数据，交通状况监控，紧急消息传播和动态路线规划。第一个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，从实验室组装的车载PC开始，到服务和应用程序。该平台是为车辆网络定义特定的网络架构和协议栈的垫脚石。这项研究可以对交通安全产生重大影响。它不仅可以减少事故造成的人员伤亡，而且还可以大大减少与这些事故相关的财务成本。此外，它还可以通过提供实时交通信息来帮助驾驶员做出更好的路线规划决策，从而减少燃油消耗和污染。主要的预期成果是一个车载网络协议栈和一个原型车载计算平台。该协议栈由几个新的、车辆特定的层组成，例如（i）数据验证和缓存，（ii）存储和转发消息路由，（iii）网内处理，以及（iv）支持移动的查询的应用层。本研究也发展了一个位置感知的GPRS/3G链路，有效地路由高优先级的消息之间断开的IEEE 802.11为基础的ad hoc网络的订阅框架。最后，它产生了一个新的研究交通建模和车辆网络系统的评估方法。将与主要汽车制造商的研究实验室联系，建立合作关系并进行技术转让。

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 first objective is to design and implement a flexible and efficient vehicular computing platform, bottom-up, starting from a car PC assembled in the lab, up to services and applications. This platform is a stepping stone toward defining a network architecture and protocol stack specific to vehicular networks.This research can have a major impact on traffic safety. Not only it can reduce the accidents' cost in human lives, but also can significantly decrease the financial costs associated with these accidents. Furthermore, it can reduce fuel consumption and pollution by providing real-time traffic information to help drivers make better route planning decisions. The main expected results are a vehicular network protocol stack and a prototype vehicular computing platform. The protocol stack consists of several new, vehicle-specific layers such as (i) Data Validation and Caching, (ii) Store and Forward Message Routing, (iii) In-Network Processing, and (iv) Application Layer supporting mobile queries. This research also develops a location-aware publish-subscribe framework that uses GPRS/3G links to efficiently route high-priority messages between disconnected IEEE 802.11-based ad hoc networks. Finally, it produces a new study of traffic modeling and an evaluation methodology for vehicular networking systems. Research labs of major car manufacturers will be contacted to establish collaborations and perform technology transfer.
