This talk introduces a Trajectory-Based Data Forwarding (TBD) scheme, tailored for the data forwarding for the Internet access
in vehicular ad-hoc networks. We consider the scenarios in which Internet access points are sparsely deployed not only
to provide the Internet applications (such as email, web surfing, and file download), but also to receive the road-side reports of
time-critical information (such as driving accident and hazard). Since the Internet access points have limited communication
coverage, a vehicular ad-hoc network is needed to forward data packets to the access points. State-of-the-art schemes have
demonstrated the effectiveness of their data forwarding strategies by exploiting known vehicular traffic statistics (e.g., densities
and speeds) in such a network. These results are encouraging; however, further improvements can be made by taking advantage
of the growing popularity of GPS-based navigation systems. This work presents the first attempt to investigate how to effectively
utilize vehicles’ trajectory information for the Internet access in a privacy-preserving manner. In our design, the trajectory
information is combined with the traffic statistics to improve the performance of data forwarding from the moving vehicles to the
Internet access points in road networks, and also vice versa. Through theoretical analysis and extensive simulation, it is shown
that our design outperforms the existing scheme in terms of both the data delivery delay and packet delivery ratio under a variety
of vehicular traffic conditions.
