Abstract

This article addresses the design of an architecture for ad hoc peer-to-peer networking of neighboring vehicles to help achieve near-instantaneous communication for safety applications such as collision avoidance warnings. We propose a local peer group (LPG) architecture to organize neighboring vehicles that have frequently changing neighbors and have no inherent relationships with one another. We study two architectural alternatives for LPG in this article, and consider areas of improvement for ad hoc vehicle networking protocols to support safety communications including multihop throughput, connection setup time, and configuration.
