As multiprocessor systems become more complex their reliability will need to increase as well In this paper we propose a novel technique which is applicable to a wide variety of distributed real time systems especially those exhibiting data parallelism We assert that for high reliability a combination of system level fault tolerance and application level fault tolerance works best In many syste...

Enterprise applications can be structured as domains, where each domain contains objects that are replicated for fault tolerance, with the replication being managed by a fault tolerance infrastructure local to the domain. Gateways can allow unreplicated clients to bene t from the fault tolerance services of the replicated servers, without compromising replica consistency within the fault tolera...

Wireless sensor networks (WSNs) have wide variety of applications and provide limitless future potentials. Nodes in WSNs are prone to be failure due to energy depletion, hardware failure, communication link errors, malicious attack, and so on. Therefore, fault tolerance is one of the critical issues in WSNs. The chapter investigates current research work on fault tolerance in WSNs. We study how...

Software fault-tolerance techniques have been widely used in computing systems to achieve high level of quality. Rejuvenation, a modern software fault-tolerance technique, has attracted a large number of researchers in software engineering area. Evaluating the effectiveness and feasibility of this technique becomes extremely important in selecting, comparing and applying it in actual software s...

To achieve fully autonomous systems, fault tolerance is often employed. Fault tolerance is the ability to continue operation in the presence of faults. Fault diagnosis is an essential component of fault tolerance, especially for autonomous robotics. It is the process of determining as much information as possible about the fault, especially the origin of the fault. However, a real time fault di...

The structures for the expression of fault-tolerance provisions into the application software are the central topic of this paper. Structuring techniques answer the questions \How to incorporate fault-tolerance in the application layer of a computer program" and \How to manage the faulttolerance code". As such, they provide means to control complexity, the latter being a relevant factor for the...

An important objective of software fault tolerant systems should be to provide a fault-tolerance infrastructure in a manner that minimizes the effort required by the application developer. In the limit, the objective is to provide fault tolerance transparently to

Service-oriented systems are usually composed by heterogeneous Web services, which are distributed across the Internet and provided by organizations. Building highly reliable service-oriented systems is a challenge due to the highly dynamic nature of Web services. In this paper, the authors apply software fault tolerance techniques for Web services, where the component failures are handled by f...

In this paper, we present some of the fault tolerance management mechanisms being implemented in the Multi-μ architecture, namely its support for replica non-determinism. In this architecture, fault tolerance is achieved by node active replication, with software based replica management and fault tolerance transparent algorithms. A software layer implemented between the application and the real...
