Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...

Supporting both real-time and fault-tolerance properties in systems is challenging because real-time systems require predictable end-to-end schedules and bounded temporal behavior in order to meet task deadlines. However, system failures, which are typically unanticipated events, can disrupt the predefined real-time schedule and result in missed task deadlines. Such disruptions to the real-time...

We focus on synthesis techniques for transforming existing fault-intolerant real-time programs to fault-tolerant programs that provide phased recovery. A fault-tolerant program is one that satisfies its safety and liveness specifications as well as timing constraints in the presence of faults. We argue that in many commonly considered programs (especially in mission-critical systems), when faul...

A desired property of large distributed systems is self adaptability against the faults that occur more frequently as the size of the distributed system grows. Self-stabilizing protocols provide autonomous recovery from finite number of transient faults. Fault-containing selfstabilizing protocols promise not only self-stabilization but also containment of faults (quick recovery and small effect...

The device-level size and complexity of reconfigurable architectures makes fault tolerance an important concern in system design. In this paper, we introduce a fully-automated fault recovery system for networked systems which contain FPGAs. If a fault is detected that can not be addressed locally, fault information is transferred to a reconfiguration server. Following design recompilation to av...

The Eager, Lazy and Movement-based strategies are used in mobile computing system when handoff. They result in performance loss while moving the whole checkpoint on fault-free or slow recovery while not moving any checkpoint until recovery. In the paper, a compromise strategy is proposed. The whole recovery information are broken into two parts, which one little part with high-priority should b...

In this paper, we propose a fault-tolerant scheme for generating global sequence numbers for total ordering in group communication. Our method is based on the notion of quorums, which have been used mostly to solve the mutual exclusion problem. In our scheme, each process in the group may initiate the generation of sequence numbers independently for messages emitted by itself. For the sake of e...

In this paper we consider the design and the evaluation of a fault-tolerant multiprocessor with a rollback recovery mechanism. The rollback mechanism Is based on the hardware recovery block which is a hardware equivalent to the software recovery block. The hardware recovery block is constructed by consecutive state-save operations and several state-save units in every processor and memory modul...

FPGAs can be used for the design of autonomic reliable systems. Advantages are reconfiguration and flexibility in the design. However commercial FPGAs are first prone to errors. Second, the design flow is not yet supported for the use of fault tolerance techniques like Built-In Self-Tests. Fault tolerance can be reached through error detection and fault recovery. Most error detection techniques...
