Fault tolerance of distributed systems by information pattern reconfiguration in the publisher/subscriber communication scheme

Given a fault tolerance strategy and a distributed control system, the set of recoverable faults depends on the information pattern that is implemented. This paper shows that fault tolerance can be achieved, when possible, by the reconfiguration of the information pattern. A necessary and sufficient recoverability condition is provided, and sub-optimal solutions are developed for actuator and sensor faults under system reconfiguration.
