Executive Summary

Vehicular Ad-hoc NETworks(VANETs) can facilitate many applications such as road safety, intelligent transportation and advertising. These applications usually call for multi-hop data delivery from access points to moving vehicles with user specified delay requirements. However, most existing routing protocols for VANETs only focus on message forwarding from vehicles to access points or take no account of the delay constraint. In this paper, the authors focus on the development of a carry-and-forward scheme that delivers data from access points to vehicles. Utilizing the vehicle's trajectory obtained from the navigation system, they propose TaDB, a Trajectory-assisted Delay-Bounded Message Delivery Algorithm.
