Packet-based on-chip interconnection networks, or Network-on-Chips (NoCs) are progressively replacing global on-chip interconnections in Multi-processor System-on-Chips (MP-SoCs) thanks to better performances and lower power consumption. However, modern generations of MP-SoCs have an increasing sensitivity to faults due to the progressive shrinking technology. Consequently, in order to evaluate...

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 order to solve effectively the problem of evaluating the wireless sensor network fault tolerance, this paper presents an evaluation index of the topological tolerance for failure node according to the ability of the topology keeping network connect and cover in case of existing failure nodes and establishes a quantitative evaluation model of topology fault tolerance according to semi-Markov ...

The OMG’s Real-Time CORBA (RT-CORBA) and FaultTolerant CORBA (FT-CORBA) specifications make it possible for today’s CORBA implementations to exhibit either real-time or fault tolerance in isolation. While real-time requires a priori knowledge of the system’s temporal operation, fault tolerance necessarily deals with faults that occur unexpectedly, and with possibly unpredictable fault recovery ...

In this paper, we focus on automated addition of fault-tolerance to an existing fault-intolerant realtime program. We consider three levels of fault-tolerance, failsafe, nonmasking, and masking, based on the properties satisfied in the presence of faults. Furthermore, for failsafe and masking fault-tolerance, we introduce two cases, soft and hard, based on satisfaction of timing constraints in ...

While there has been signiicant advances in fault tolerance research, the eeort has focused on the design of individual fault-tolerant systems or methodologies. Recently, some research has been initiated to develop fault tolerance paradigms that can be used to provide a spectrum of fault tolerance levels. In this paper, we present the design of a fault tolerance framework that can be used to su...

This paper describes and illustrates the application of a strategy for testing fault tolerance by means of fault injection. The proposed approach encompasses a method for modelling fault tolerance together with a strategy for testing several classes of fault tolerance mechanisms. The modelling approach distinguishes two main abstraction levels: (i) a data flow diagram of the general organisatio...

Recently the component‐based approach has become a major trend in intelligent service robot development due to its reusability and productivity. The framework in a component‐based system should provide essential services for application components. However, to our knowledge the existing robot frameworks do not yet support fault tolerance service. Moreover, it is often be...
