The AOFSN network consists of three-level hierarchical sensor network architectures. The first two levels consist of active interrogation and remote nodes (RNs) and the third level, called the sensor subnet (SSN), consists of passive Fiber Bragg Gratings (FBGs) and a few switches. The switch architectures in the RN and various SSNs to improve the reliability and scalability of AOFSN are studied. Two SSNs with a regular topology are proposed to support simple routing and scalability in AOFSN: square-based sensor cells (SSC) and pentagon-based sensor cells (PSC). The reliability and scalability are evaluated in terms of the available sensing coverage in the case of one or multiple link failures.<\/jats:p>","DOI":"10.3390\/s100402901","type":"journal-article","created":{"date-parts":[[2010,3,29]],"date-time":"2010-03-29T11:15:16Z","timestamp":1269861316000},"page":"2901-2918","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Investigation on Reliability and Scalability of an FBG-Based Hierarchical AOFSN"],"prefix":"10.3390","volume":"10","author":[{"given":"Li-Mei","family":"Peng","sequence":"first","affiliation":[{"name":"School of Information Technology, Chonbuk National University, Jeonju 561-756, Korea"},{"name":"GRID Middleware Research Center of ICC, Korea Advanced Institute of Science and Technology, Taejon, 305, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin-Wan","family":"Li","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Advanced Optical Communication Systems and Networks, Department of Electronic Engineering, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Won-Hyuk","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information Technology, Chonbuk National University, Jeonju 561-756, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young-Chon","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Information Technology, Chonbuk National University, Jeonju 561-756, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2010,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1109\/LPT.2002.806088","article-title":"A Novel Fiber-Laser-Based Sensor Network with Self-Healing Function","volume":"15","author":"Peng","year":"2003","journal-title":"IEEE Photonic.
