Vehicular communication systems (VCS) are an emerging information and communication technology aimed to improve road safety, support intelligent transportation, and provide infotainment services to users on roads. Various R&D activities around the globe have been carrying out in recent years for the technology development. This research project is to investigate and develop novel engineering solutions for efficiently providing various vehicular communication services, especially for high-rate large-volume data transfer in in-vehicle Internet access, by taking advantage of heterogeneous wireless networking technologies including cellular networks, WiFi, and the dedicated short-range communications (DSRC). In particular, this project will develop (i) an intelligent data traffic offloading scheme from cellular networks to WiFi/DSRC networks, (ii) an inter-working framework between cellular networks and WiFi/DSRC networks for seamless service delivery in VCS, and (iii) dynamic access on available TV radio spectrum for data transfer in a vehicular environment, making use of the property that vehicle movement trajectories are limited to road geometry. The project will help to push the frontier of wireless communications to a new domain for VCS applications. It will develop networking algorithms/protocols that are critical for connecting mobile users on roads in a highly dynamic network topology. The research outcomes will be widely disseminated in archival journals, premier conference proceedings, technical seminars, and invention disclosures and patents. This project, pursued in close collaboration with corporate industrial sponsor, General Motors of Canada Limited (GM), will make a significant contribution to the future VCS development, and result in significant benefits to Canadian users in road safety, transportation efficiency, mobile Internet ac-cess, and many potential new on-road services and applications. Four graduate students will work on this project, doing research in the latest development of vehicular communications, emerging as expert additions to the Canadian high technology industry labor force.

车载通信系统（Vehicular Communication Systems，简称VCS）是一种新兴的信息和通信技术，旨在提高道路安全，支持智能交通，并为道路上的用户提供信息娱乐服务。近年来，为了技术开发，在地球仪范围内开展了各种研究与开发活动。该研究项目旨在研究和开发新型工程解决方案，通过利用蜂窝网络、WiFi等异构无线网络技术，高效地提供各种车载通信服务，特别是车载互联网接入中的高速大容量数据传输。和专用短程通信（DSRC）。具体而言，该项目将开发（i）从蜂窝网络到WiFi/DSRC网络的智能数据流量卸载方案，（ii）蜂窝网络与WiFi/DSRC网络之间的互通框架，以实现无线网络中的无缝服务交付，以及（iii）在车辆环境中动态访问可用的电视无线电频谱以进行数据传输，利用车辆运动轨迹受限于道路几何形状的特性。 该项目将有助于推动无线通信的前沿到一个新的领域，为物联网应用。它将开发联网算法/协议，这些算法/协议对于在高度动态的网络拓扑结构中连接道路上的移动的用户至关重要。研究成果将在档案期刊、主要会议记录、技术研讨会、发明披露和专利中广泛传播。该项目与企业赞助商加拿大通用汽车有限公司（GM）密切合作，将为未来的道路交通发展做出重大贡献，并在道路安全、运输效率、移动的互联网接入和许多潜在的新道路服务和应用方面为加拿大用户带来重大利益。四名研究生将在这个项目上工作，研究车辆通信的最新发展，成为加拿大高科技产业劳动力的专家补充。
