Enabling High-Bandwidth Vehicular Content Distribution

Executive Summary

The authors present VCD, a novel system for enabling high-bandwidth content distribution in vehicular networks. In VCD, a vehicle opportunistically communicates with nearby Access Points (APs) to download the content of interest. To fully take advantage of such transient contact with APs, they proactively push content to the APs that the vehicles will likely visit in the near future. In this way, vehicles can enjoy the full wireless capacity instead of being bottlenecked by the Internet connectivity, which is either slow or even unavailable. They develop a new algorithm for predicting the APs that will soon be visited by the vehicles.
