Resource efficient redundancy using quorum-based cycle routing in optical networks [PDF]

open access: yes, 2015
In this paper we propose a cycle redundancy technique that provides optical networks almost fault-tolerant point-to-point and multipoint-to-multipoint communications.

Research on Dual Security Control for a Non-Linear CPS with Multi-Objective Constraints under DoS Attack and Actuator Fault: An Active-Passive Attack-Tolerant Approach

open access: yesJournal of Control Science and Engineering, 2022
Based on the discrete event-triggered communication scheme (DETCS), a codesign method of dual security control and communication for the non-linear cyberphysical system (CPS) with denial-of-service (DoS) attack and actuator fault is studied under multi ...

An approach to rollback recovery of collaborating mobile agents [PDF]

open access: yes, 2004
Fault-tolerance is one of the main problems that must be resolved to improve the adoption of the agents' computing paradigm. In this paper, we analyse the execution model of agent platforms and the significance of the faults affecting their constituent ...

Fault Tolerant Control of Five-Level Inverter Based on Redundancy Space Vector Optimization and Topology Reconfigruation

open access: yesIEEE Access, 2020
Compared with two-level and three-level inverters, five-level inverters have more redundant space vectors to implement flexible control strategy. A fault tolerance method for open circuit fault of power tube in Neutral Point Clamped (NPC) five level ...

Combined Time and Information Redundancy for SEU-Tolerance in Energy-Efficient Real-Time Systems

open access: yes, 2006
Recently the trade-off between energy consumption and fault-tolerance in real-time systems has been highlighted. These works have focused on dynamic voltage scaling (DVS) to reduce dynamic energy dissipation and on time redundancy to achieve transient ...

Assessing Asymmetric Fault-Tolerant Software [PDF]

open access: yes, 2010
The most popular forms of fault tolerance against design faults use "asymmetric" architectures in which a "primary" part performs the computation and a "secondary" part is in charge of detecting errors and performing some kind of error processing and ...

A Framework-Based Approach for Fault-Tolerant Service Robots

open access: yesInternational Journal of Advanced Robotic Systems, 2012
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 ...

Algorithmic Based Fault Tolerance Applied to High Performance Computing

open access: yes, 2008
We present a new approach to fault tolerance for High Performance Computing system. Our approach is based on a careful adaptation of the Algorithmic Based Fault Tolerance technique (Huang and Abraham, 1984) to the need of parallel distributed computation.

Upper bounds on fault tolerance thresholds of noisy Clifford-based quantum computers [PDF]

open access: yes, 2010
We consider the possibility of adding noise to a quantum circuit to make it efficiently simulatable classically. In previous works, this approach has been used to derive upper bounds to fault tolerance thresholds-usually by identifying a privileged ...
