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.
