Trajectory-Based Statistical Forwarding for Multi-Hop Infrastructure-to-Vehicle Data Delivery
This paper proposes Trajectory-based Statistical Forwarding (TSF) scheme, tailored for the multi-hop data delivery from infrastructure nodes (e.g., Internet access points) to moving vehicles in vehicular ad-hoc networks. To the authors' knowledge, this paper presents the first attempt to investigate how to effectively utilize the packet destination vehicle's trajectory for such an infrastructure-to-vehicle data delivery. This data delivery is performed through the computation of a target point based on the destination vehicle's trajectory that is an optimal rendezvous point of the packet and the destination vehicle. TSF forwards packets over multi-hop to a selected target point where the vehicle is expected to pass by. Such a target point is selected optimally to minimize the packet delivery delay while satisfying the required packet delivery probability.
