Using FTT and stars to simplify node replication in CAN-based systems

Nodes, among the components of distributed embedded systems, exhibit the greatest permanent failure rate. Thus, providing tolerance to nodes faults is mandatory whenever high-reliability is required, being node replication the most common technique for that purpose. This paper proposes a novel technique suitable for CAN-based systems that simplifies existing approaches taking advantage of a star topology and the FTT protocol.
