RECOVERY IN DISTRIBUTED SYSTEMS FROM SOLID FAULTS
IFAC Proceedings Volumes, 1992Abstract Our study is dealing with recovery processes in a distributed environment in case of solid fault like transient or permanent. The recovery mechanism we presented can be based on one of several strategies (six) where some of them involve saving information messages exchanged between cooperating application processes. This exhaustive number is

Recovery in fault-tolerant distributed microcontrollers
Proceedings International Conference on Dependable Systems and Networks, 2002The paper describes the use of fault tolerance in a microcontroller node to be used in a network of embedded processors. It is primarily motivated by long-life space applications where radiation-induced transient errors will be a frequent occurrence, and a few chip failures may be expected before a mission is completed.

Fault recovery by nominal trajectory tracking
2008 American Control Conference, 2008Fault accommodation is meant to control the faulty system so as to preserve a given functionality. In model matching, the state dynamics is wished to be fault-invariant, leading to the family of pseudo-inverse and modified pseudo- inverse methods. In this paper, rather than the closeness between the faulty and the nominal system matrices, it is the ...

Fault Detection and Recovery Techniques in CUTLASS
IFAC Proceedings Volumes, 1983Abstract CUTLASS is a software system for power station control and related process control applications using functionally distributed networks of computers in power stations. The paper describes the design approach employed to detect, contain and recover from failures both in the hardware and in the application software.

Recovery Schemes for Fast Fault Recovery on GMPLS Network
2008In this research, we proposed two types of fault recovery schemes designed by combining the protection and the restoration methods in order to increase the survivability of GMPLS networks. The first method is a transformation of the 1+1 protection method where it consumes more resources than the 1+1 protection method but has a faster fault recovery ...

Fault recovery mechanism for multiprocessor servers
Proceedings of IEEE 27th International Symposium on Fault Tolerant Computing, 2002Achieving higher reliability in open server computer systems with low cost has been an increasing interest recently. To satisfy this general demand, we propose a new fault recovery mechanism. We extended the recovery cache scheme to adapt to state-of-the-art multiprocessor server computer systems, and built a system level fault recovery mechanism.

The SLA-Compatible Fault Management Model for Differentiated Fault Recovery
2006The paper proposes a SLA-compatible fault management model for differentiated fault recovery after introducing SLA, service-differentiated and existing fault recovery techniques, and gives the basic ideas, detailed processing schemes and consideration of this model.

Actuator fault recovery study based on post-fault time analysis
IFAC Proceedings Volumes, 2011Under Fault-Tolerant control (FTC) framework, the present work discusses the actuator fault recoverability in relation with the fault occurrence, the fault detection and the fault accommodation delays. A performance index dealing with the variation between the nominal dynamic and the faulty one is defined and computed for different post-fault time ...

SDWDS: Fault Recovery Automation in IoTs
2018 15th Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2018To assist various intelligent applications, IoT devices send their monitored data to Internet for further process. WiFi access points (APs) would be a candidate to support data transmission in IoTs due to its large wireless service coverage and low cost.

Evaluation fault detection and fault recovery of microcontroller by fault injection
1998Microcontroller in dyad are used for increased reliability and fault tolerance. Depending on two types of software the behaviour of such system could be for increased persistency or for increased integrity. Redundancy is incorporated in software in form of time redudancy, data multiplication, retry etc. Microcontrollers in dyad are loosely coupled with
