Abstract
The system’s self diagnosis capability is a critical indicator for the reliability of multiprocessor systems, which plays a key role in ensuring the smooth operation of big data processing and cloud computing. Cycle structures, which bring redundant paths for secure communication, enhance network reliability significantly. Based on cyclic connectivity, cyclic diagnosability has been proposed and has witnessed a small amount of progress. Although the metric relationship between cyclic connectivity and cyclic diagnosability has been established, the flexibility of generating graph of Cayley graphs prevents this metric relationship from being directly applied to characterize the cyclic diagnosability of all Cayley graphs generated by transposition trees. In this paper, we classify the generating transposition trees based on the diameter and the number of matchings, and determine the cyclic diagnosability of Cayley graphs generated by these transposition trees under PMC and MM* models.
期刊介绍:
The aim of Discrete Applied Mathematics is to bring together research papers in different areas of algorithmic and applicable discrete mathematics as well as applications of combinatorial mathematics to informatics and various areas of science and technology. Contributions presented to the journal can be research papers, short notes, surveys, and possibly research problems. The "Communications" section will be devoted to the fastest possible publication of recent research results that are checked and recommended for publication by a member of the Editorial Board. The journal will also publish a limited number of book announcements as well as proceedings of conferences. These proceedings will be fully refereed and adhere to the normal standards of the journal.
Potential authors are advised to view the journal and the open calls-for-papers of special issues before submitting their manuscripts. Only high-quality, original work that is within the scope of the journal or the targeted special issue will be considered.
