This paper is aimed at reviewing the notion of Byzantine-resilient distributed computing systems, the relevant protocols and their possible applications as reported in the literature. The three agreement problems, namely, the consensus problem, the interactive consistency problem, and the generals problem have been discussed. Various agreement protocols for the Byzantine generals problem have been summarized in terms of their performance and level of fault-tolerance. The three classes of Byzantine agreement protocols discussed are the deterministic, randomized, and approximate agreement protocols. Finally, application of the Byzantine agreement protocols to clock synchronization is highlighted.
The paper deals with the relation between diagnosability of deterministic I/O automata and state equivalence. Diagnosability criteria are formulated in terms of the existence of equivalent automaton states. The absenc...

Event-based control aims at reducing the information exchange over the communication network in control systems. This paper presents an extension of an existing event-based state-feedback approach that reduces the com...

If an automaton has a set of unobservable states, then the observation result cannot be improved as long as the automaton moves within this set. It is, therefore, reasonable to reduce the automaton and: hence: the com...

The paper deals with the determination of input sequences for which the faults occurring in discrete-event systems described by deterministic I/O automata can be detected and identified. The basis for this method is p...

Model-based fault detection relies on checking the discrepancy between the measurements obtained from a monitored process and its model. In general, the model representing the process behaviour has substantial uncerta...
