Multi-MTTR Asynchronous-Asymmetric Channel-Hopping Sequences for Scalable Cognitive Radio Networks

IEEE Transactions on Cognitive Communications and Networking, 2018
In this paper, a family of channel-hopping (CH) sequences, so-called multi-maximum time-to-rendezvous (MTTR) asynchronous-asymmetric prime sequences (MAAPSs), for cognitive radio networks (CRNs) is designed and analyzed. They have known and enlarged cardinality (for the benefit of user identification), full degree of rendezvous, and pairwise shift ...

MTTR Lower Bound and Construction of Synchronous-Asymmetric Channel-Hopping Sequences for Cognitive Radio Networks

2018 3rd International Conference on Computer and Communication Systems (ICCCS), 2018
In this paper, a family of synchronous-asymmetric channel-hopping (CH) sequences for cognitive radio (CR) networks is constructed and their maximum-time-to-rendezvous (MTTR) lower bound is derived. The new sequences achieve full degree-of-rendezvous and optimal MTTR.

Is it safe to use MTTF/(MTTF + MTTR) for the availability?

Proceedings of the 29th European Safety and Reliability Conference (ESREL), 2019
International audiencePractitioners in reliability and system safety know that the asymptotic availability of a repairable component is given by the ratio MTTF/(MTTF + TMTR). The transient behavior of the availability is less well known.

A System’s MTTR Allocation Method Based on the Time Factors

Advanced Materials Research, 2012
The maintenance allocation methods are important in the design and maintenance of product. However, these methods have lots of deficiencies in practical application, which is inconsistent with the purpose of the maintenance allocation. To allocate the system MTTR (Mean Time to Repair) to the subsystems more precisely and reasonably, a better model is ...

PC software solutions for MTTR predictions

Proceedings., Annual Reliability and Maintainability Symposium, 2003
The various methods available in computerized maintainability prediction methods (for MIL-HDBK-472, Notice 1, Procedure 5) and the relative factors that should be considered in evaluating software techniques for MTTR (mean time to repair) and associated predictions are discussed.

Microprocessing to Reduce MTTR of Analog Systems

Annual Reliability and Maintainability Symposium, 1984. Proceedings., 2005
This paper presents a cost-effective method to reduce the Mean Time To Repair (MTTR) of analog systems by reducing the amount of time required to perform the elemental task of fault isolation. The traditional technique of manual troubleshooting using test points and external test equipment to perform the fault isolation task is compared with a ...
