Fault Tolerance is a configuration that prevent a computer or network device from failing in the event of unexpected problem or error such as hardware failure, link failure, unauthorized access, variations in the configuration of different systems and system running out of memory or disk space. The integration of fault tolerance measures with scheduling gains much importance. Workflow managemen...

The array erasure code, an ideal method for fault tolerance in storage systems, however, is obstructed by its impossibility to set the fault tolerant ability according to dynamic application environment for practical purpose. In view of this, this paper presents a new class of array erasure codes, with the greatest contribution to the array codes which can be obtained according to the preset nu...

This paper presents penalty terms for fault tolerance enhancement. We argue that the use of conventional learning algorithms leads to networks that have solutions that are non-optimally distributed and hence susceptible to faults. In addition we assert that fault tolerance will become an increasingly important factor in practical applications of neural networks. To address these issues we prese...

The embedding of fault tolerance provisions into the application layer of a programming language is a nontrivial task that has not found a satisfactory solution yet. Such a solution is very important, and the lack of a simple, coherent and effective structuring technique for fault tolerance has been termed by researchers in this field as the “software bottleneck of system development”. The aim ...

The ability to guarantee that a system will continue to operate correctly under degraded conditions is key to the success of adopting multi-agent systems (MAS) as a paradigm for designing complex agent based fault tolerant systems. In order to provide such a guarantee, practically usable tools and techniques for verifying fault tolerant MAS architectures are urgently required. In this paper we ...

On Strong Fault Tolerance (or Strong Menger-Connectivity) of Multicomputer Networks. (August 2004) Eunseuk Oh, B.S., Hallym University, Korea; M.S., Ewha Womans University, Korea Chair of Advisory Committee: Dr. Jianer Chen As the size of networks increases continuously, dealing with networks with faulty nodes becomes unavoidable. In this dissertation, we introduce a new measure for network fau...

As robot tasks in space nuclear and medical environments be come more widespread the issues of reliability and safety for robots are becoming more critical Attempts to address these is sues have resulted in a recent surge of activity in robot fault tol erance We concentrate on fault tolerance in the robot controller and highlight the importance and potential of multiprocessor con trol architect...

We present a model for application-level fault tolerance for parallel applications. The objective is to achieve high reliability with minimal impact on the application. Our approach is based on a full replication of all parallel application components in a distributed wide-area environment in which each replica is independently scheduled in a different site. A system architecture for coordinati...

In general, faults cannot be prevented; instead, they need to be tolerated to guarantee certain degrees of software dependability. We develop a theory for fault tolerance for a distributed pi-calculus, whereby locations act as units of failure and redundancy is distributed across independently failing locations. We give formal definitions for fault tolerant programs in our calculus, based on th...

Fault tolerance is a crucial design consideration for missioncritical distributed real-time and embedded (DRE) systems, such as avionics mission computing systems, and supervisory control and data acquisition systems. Increasingly more of these systems are created using emerging middleware standards, such as publish-subscribe communication services and component based architectures. Most previo...
