While there have been extensive studies for fault resilience in real-time embedded systems, investigations from the cyber-physical systems (CPS) perspective are still much needed, as CPS faults occur not just from abnormal conditions in the software\/hardware of the system but also from the physical environment in which the system operates. At the same time, in addition to conventional fault-tolerance strategies embedded in the software\/hardware of the target system, CPS faults could be mitigated via some strategic systems re-configuration made available by the physical environment. This article presents a design and implementation for CPS fault-resilient data communication in the context of IIoT networks running LoRaWAN, a low-power wide-area networking standard. The proposed design combines collaborative IIoT end devices plus a network gateway piggybacked on a third-party cruising object that is part of the environment. With the focus on data communication, the study illustrates challenges and opportunities to address CPS fault resilience while meeting the needs for energy efficiency and communication timeliness that are common to IIoT systems. The implementation of the design is based on ChirpStack, a widely used open source framework for LoRaWAN. The results from experiment and simulation both show that the proposed scheme can tolerate limited errors of data communication while saving operating energy and maintaining timeliness of data communication to some extent.<\/jats:p>","DOI":"10.1145\/3639571","type":"journal-article","created":{"date-parts":[[2024,1,4]],"date-time":"2024-01-04T21:34:48Z","timestamp":1704404088000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["On Cyber-Physical Fault Resilience in Data Communication: A Case From A LoRaWAN Network Systems Design"],"prefix":"10.1145","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0919-8781","authenticated-orcid":false,"given":"Chao","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Taiwan Normal University, Taipei City, Taiwan (R.O.C.)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9301-5384","authenticated-orcid":false,"given":"Cheng-Hsun","family":"Chuang","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Taiwan Normal University, Taipei City,  Taiwan (R.O.C.)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8276-3235","authenticated-orcid":false,"given":"Yu-Wei","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Taiwan Normal University, Taipei City,  Taiwan (R.O.C.)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4233-4354","authenticated-orcid":false,"given":"Yun-Fan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Taiwan Normal University, Taipei City, Taiwan (R.O.C.)"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,7,13]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"Fault Tolerance: Principles and Practice","author":"Anderson T.","year":"1981","unstructured":"T.
