Abstract

A method and system of distributed communication of independent autonomous vehicles to provide redundancy and performance are disclosed. In one embodiment, a set of autonomous vehicles operates in a geographically proximate area through which peer-to-peer communication sessions are established between nearby ones of the set of autonomous vehicles through an ad-hoc network based on a present geo-spatial location of each one of the set of autonomous vehicles in communication proximity to preferred adjacent ones of the set of autonomous vehicles. A central server directly coupled to each of the set of autonomous vehicles establishes centralized communication paths with each of the set of autonomous vehicles through a wide area network. The centralized server processes a communication from adjacent ones of the set of autonomous vehicles when an error condition is detected in an operational mode of a non-functional vehicle that has lost communication with the central server.
