Graph theory and optical switching are simultaneously applied to these sensor networks to improve their self-healing ability; the FBG sensor network is regarded as a directed graph. Three commonly used self-short-circuit algorithms are compared in terms of the self-healing capabilities that they provide to the optical fiber sensor network. Among these, the shortest-path faster algorithm achieved a high, nearly 90% repair accuracy and had an average repair time of 0.103\u2009s, the shortest in this study. The newly designed FBG self-healing network can be reorganized and repaired when local damage occurs, thereby improving its reliability.<\/jats:p>","DOI":"10.1155\/2022\/5717041","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T22:35:09Z","timestamp":1659566109000},"page":"1-9","source":"Crossref","is-referenced-by-count":7,"title":["Self-Healing and Shortest Path in Optical Fiber Sensor Network"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3126-2105","authenticated-orcid":true,"given":"Xingliu","family":"Hu","sequence":"first","affiliation":[{"name":"School of Intelligence Science and Control Engineering, Jinling Institute of Technology, Nanjing 211169, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2634-4824","authenticated-orcid":true,"given":"Haifei","family":"Si","sequence":"additional","affiliation":[{"name":"School of Intelligence Science and Control Engineering, Jinling Institute of Technology, Nanjing 211169, China"},{"name":"College of Intelligent Systems Science and Engineering, Harbin Engineering University, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4229-9149","authenticated-orcid":true,"given":"Junhui","family":"Mao","sequence":"additional","affiliation":[{"name":"School of Automation and School of Artificial Intelligence, Nanjing University of Posts and Telecommunications, Nanjing 210003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8648-9016","authenticated-orcid":true,"given":"Yizhi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Intelligence Science and Control Engineering, Jinling Institute of Technology, Nanjing 211169, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"2","key":"1","doi-asserted-by":"crossref","first-page":"595","DOI":"10.1109\/TIM.2018.2851698","article-title":"Monitoring of overhead transmission conductors subjected to static and impact loads using fiber Bragg grating sensors","volume":"68","author":"D.
