Abstract This article investigates the fault estimation and tolerant control (FTC) problems for linear stochastic uncertain systems. By introducing fictitious noise, is augmented as part of systems state, then a robust estimator proposed to simultaneously obtain state estimation. Based on estimated information, active FTC presented eliminate impact fault. Finally, simulation example conducted d...

The purpose of this paper is to investigate how several innovative techniques, not all initially intended for fault-tolerance, can be applied in providing fault tolerance of complex mobile agent systems. Due to their roaming nature, mobile agents usually run on Java-based platforms, which ensures full portability of mobile code. The rst part of the paper discusses speciic characteristics of mob...

Critical infrastructures provide services upon which society depends heavily; these applications are themselves dependent on distributed information systems for all aspects of their operation and so survivability of the information systems is an important issue. Fault tolerance is a key mechanism by which survivability can be achieved in these information systems. We outline a specification-bas...

Real time systems are systems in which there is a commitment for timely response by the computer to external stimuli. Real time applications have to function correctly even in presence of faults. Fault tolerance can be achieved by either hardware or software or time redundancy. Safety-critical applications have strict time and cost constraints, which means that not only faults have to be tolera...

A persistent publish/subscribe messaging model allows the creation of an application-independent fault-tolerant layer for multi-agent systems. We propose a layer which is capable of supporting heterogenous agent platforms from different vendors. This layer is a three-tier application, which is accessible from multi-agent systems via web-services or a persistent publish/subscribe messaging syste...

As computing systems become an increasingly integral part of our lives, the need for fault-tolerance and security in these systems is constantly growing. These computing systems include telecommunication, power systems, collaborative group-oriented systems, sensor networks and electronic commerce. Also, the faulttolerance requirement of a system tends to evolve with new technology. Hence, one n...
