A Wireless Mesh Network for Real-Time Vehicle Guidance

This paper presents a large-scale vehicle routing architecture and the associated protocols that aim at delivering real time vehicle guidance. In the architecture presented, communication functions and vehicle route processing are separated into distinct subsystems, where the former deals with wireless communication through a roadside mesh-like network and the latter involves a design framework for low-complexity real-time vehicle routing table computation. The paper also demonstrates that the bandwidth requirement is modest, the processing requirement within the vehicle is minimal, and vehicle routing complexity can be drastically reduced.
