Most robot controllers today employ a single processor architecture As robot control requirements become more complex these serial controllers have di culty providing the desired response time Additionally with robots being used in environments that are hazardous or inaccessible to humans fault tolerant robotic systems are particularly desirable A uniprocessor control architecture cannot o er t...

Checkpointing and rollback recovery is a simple technique for fault tolerance. The state of a process is saved on a disk file from which the process can recover on the occurrence of failure. In this paper we describe the implementation of FTOP (Fault Tolerant PVM), a coordinated checkpointing library integrated with PVM. Existing PVM applications require only minor change for incorporating faul...

Fault tolerance has always been a standard feature of electronic systems intended for long-term missions. However, the high complexity of modern systems makes the incorporation of fault tolerance a difficult task. Novel approaches to fault tolerance can be achieved by drawing inspiration from nature. Biological organisms possess characteristics such as healing and learning that can be applied t...

Many fault tolerance techniques that have been devised, applied and improved over the past three decades represent general solutions to recurring problems in the design of fault tolerant computer systems. This document presents some of the best known such techniques, formatted as patterns and organized by a classification scheme into a system of patterns for fault tolerance. This pattern system...

The emergence of wireless networked sensors constitutes a hot research topic in embedded system design. Although system resource is seriously limited, operating system applied in sensors has to implement complex task scheduling, which should support concurrent operations, real-time constraint, adaptability and reliability. In this paper, we present a reliable OS scheduling scheme for wireless n...

Cloud computing is upcoming a mainstream feature of information technology. More progressively enterprises deploy their software systems in the cloud environment. The applications in cloud are usually large scale and containing a lot of distributed cloud components. Building cloud applications is highly reliable for challenging and critical research issues. Information processing systems has in...

This paper presents the design and prototype implementation of a reactive system that facilitates the fault detection and fault tolerance for a loosely integrated heterogeneous database system. The fault detection mechanism uses sensors to monitor individual databases and system objects and to detect database or system component failures. The fault tolerance mechanism uses actuators to react on...

This chapter describes a study on workflow scheduling with fault tolerance. It starts with an understanding on workflow scheduling and fault tolerance technologies independently. Next, the chapter surveys the related works on the combination field of workflow scheduling and fault tolerance technologies. Generally, these works are classified into six categories corresponding to the six fault tol...
