Today a growing number of companies have to progressionenormous amounts of statistics in a costefficientmode.The scientific community has exposed increasing interest in researching new high performance distributed computing platforms for accommodating and meeting the ever increasing computational and storage space requirements of grand challenge e-science applications. The Fault tolerance techn...

In this paper, we will consider the application of notions and techniques from fuzzy logic, fault trees, and Markov modeling to robot fault tolerance. Fuzzy logic lends itself to quantitative reliability calculations in robotics. The crisp failure rates which are usually used are not actually known, while fuzzy logic, due to its ability to work with the actual approximate (fuzzy) failure rates ...

A distributed system has a number of independent computers allied up a network and sharing middleware which enables computers to organize their behavior and behave as a single coherent system. Mobile computing system is also one of the types of distributed computing system. In this network nodes are called mobile node. It is example of the distributed computing system. There are number of issue...

This paper presented a novel decentralized fault tolerant control strategy for the control of linear multivariable processes. The multiple model based fault tolerant method is used to improve system performance (under model uncertainty and slow variation) and implement active fault tolerant control. In the mean time, we extended the decentralized unconditional stable control to multiple model c...

The need for a separate fault-management system, that is able to carry out both failure detection and reconfiguration, is becoming imperative due to the increasing complexity of fault-tolerant distributed applications. Such practice would eliminate the intricacies of the failure detection mechanisms from the application and would avoid repeating them in every program. The dependability of such ...

I present a survey of automated techniques for software fault localization. Fault localization or localizing the root cause of failure is one of the most difficult processes in software debugging. Hence, many automated techniques have emerged to help in this process. Most of these techniques are based on the principles used in real life for fault diagnosis. I have used these principles to class...

A high-resolution relative earthquake location procedure is used to image the fine-scale seismicity structure of the northern Hayward fault, California. The seismicity defines a narrow, near-vertical fault zone containing horizontal alignments of hypocenters extending along the fault zone. The lineations persist over the 15-year observation interval, implying the localization of conditions on t...

In this paper, we propose an agreement-based fault detection and recovery protocol for cluster head (CH) in wireless sensor networks (WSNs) of two level cluster hierarchy. The aim of protocol is to accurately detect CH failure to avoid unnecessary energy consumption caused by a mistaken detection process. For this, it allows each cluster member to detect its CH failure independently. Cluster me...

Multiprotocol label switching (MPLS) has become an attractive technology for the next generation backbone networks. To provide high quality services, fault tolerance should be taken into account in the design of a backbone network. In an MPLS based backbone network, the fault-tolerant issue concerns how to protect traffic in a carried path (label switched path (LSP)) against node and link failu...
