If the variables used for a checkpointing algorithm have data faults, the existing checkpointing and recovery algorithms may fail. In this paper, self-stabilizing data fault detecting and correcting, checkpointing, and recovery algorithms are proposed in a ring topology. The proposed data fault detection and correction algorithms can handle data faults; at most one per process, but in any numbe...

Fast and stable post-fault recovery is an essential part of a fault clearing strategy in HVDC grids. As the may involve de-blocking converters, unwanted oscillations be noticed voltages currents. These occur at resonant frequencies, which stem from interaction between converter grid. Methods to identify grid resonances exist, but focus mainly on control interactions instead during transient con...

This paper addresses fault-tolerant control for position mooring of a shuttle or floating production storage and offloading vessels. A complete framework for fault diagnosis is presented. A loss of a sub-sea mooring line buoyancy element and line breakage are given particular attention, since such failures might cause high-risk abortion of an oil-loading operation. With significant drift forces...

Research on fine tuning stabilization properties has received attention for more than a decade. This paper presents probabilistic algorithms for fault containment. We demonstrate two exercises in fault containment in a weakly stabilizing system, which expedite recovery from single failures, and confine the effect of any single fault to the constant-distance neighborhood of the faulty process. T...

Hard real-time systems have stringent deadline requirements, which can be guaranteed at system design time by restricting the computational model so that a careful analysis of execution-time budgets and response-time values can be performed. However, design-time guarantees are not enough in many high-integrity systems, in which some degree of run-time fault-tolerance has to be implemented as we...

In Wireless Body Area Networks (WBANs), the extremely sensitive data transmission mainly requires fault tolerance and consistent data transmission. In this study, we propose a Cluster Based Failure Detection and Recovery Technique for WBAN which presents a hierarchical architecture. Here, local nodes are connected to their Cluster Heads (CHs). Each CH is interconnected and also connected with a...
