LiveSAFETY: Localization in vehicle ad hoc networks for safety applications

随着“加拿大智能交通系统计划：走向智能交通”文件的发布，加拿大明确强调了其将我们的交通系统带入21世纪的愿望和主要目标，使其更安全，更高效，更一体化。自组织网络和传感器网络以及无线通信的最新进展使得车辆自组织网络成为实现这些目标的有希望的解决方案，但并非没有产生一系列新的具有挑战性的问题和权衡。最吸引人的应用之一，我们将集中在这个项目中，是提出一个随时随地，细粒度，可靠的时空定位发现和监控系统，用于车辆在VANets的关键安全和应急应用。Ananytime的要求意味着定位系统在计算当前位置和同步车辆时钟时必须没有延迟（例如，没有启动延迟）。这个要求是至关重要的，因为VANets的高机动性意味着稍微过时的位置信息不能被使用，甚至可能是危险的。“随时随地”的可用性是VANet定位系统面临的主要挑战。因此，我们的目标是为车辆网络和安全应用设计高效可扩展的时空定位框架。在这些类型的应用程序中，我们的本地化协议确保细粒度的本地化和同步错误是很重要的。本计画将提供学生无线通讯、车辆与无线网路系统、以及建模与仿真的必要技能。pi基本上是响应政府机构、IT产业部门和学术界在这些领域的高要求。

With the publication of the document ``An Intelligent Transportation Systems Plan for Canada: En Route toIntelligent Mobility'', Canada has highlighted clearly its desire and main objectives in bringing ourtransportation system into the 21st Century, making it safer, efficient, and integrated. Recent advances in adhoc and sensor networks and wireless communication have made vehicle ad hoc networks a promisingsolutions to achieve these goals, however not without cretaing a new set of challenging issues and trade-offs.One of the most appealing applications, we will concentrate on in this project,is to propose an anytime, anywhere, fine-grained, and reliable time-space localization discovery andmonitoring system to be used by vehicles in VANets for critical safety and emergency applications. Ananytime requirement means that the localization system must be free of delays when computing the currentposition and synchronizing the clocks of the vehicles (e.g., no startup delay). This requirement is critical,since the high mobility of VANets means that slightly outdated position information cannot be used andcould even be dangerous. The "anywhere" availablity is a major challenge in VANet localization systems.It is therefore our goals to design efficient scalable time-space localtization framework for vehicle ad hocnetworks and safety applications. In these kind of applications,it is important that our localization protocols ensure fine-grained localization and synchronization errors.This project will provide the students the necessary skills in wireless communication, vehicle ad hocnetworking systems, and modeling and simulation. The PIs are basically responding to the high demands fromgovernmental agencies, IT industrial sector and academia in these areas.
