Abstract

We introduce Virtual Ferry Networking (VFN), a novel approach to data dissemination services on mobile ad-hoc networks. VFN exploits the emergent patterns of vehicles' mobility to buffer and carry messages when immediately forwarding those messages would fail. Instead of depending on a fixed, small set of vehicles and paths for ferrying messages, VFN allows any vehicle moving along part of a virtual route to become a possible carrier for messages. VFN helps address many of the challenges with supporting distributed applications in challenging ad-hoc vehicular networks with rapidly changing topologies, fast-moving vehicles and signal-weakening obstructions such as bridges and buildings. We discuss the challenges with implementing VFN and present evaluation results from an early prototype.
