However, providing autonomous, reliable, and real-time offloaded services for such a production is an open challenge since these IIoT devices are assumed lightweight embedded platforms with limited computing performance. In this paper, we propose a pattern-identified online task scheduling (PIOTS) mechanism for the networking infrastructure, where multitier edge computing is provided, in order to handle the offloaded tasks in real time. First, historical IIoT task patterns in every timeslot are used to train a self-organizing map (SOM), which represents the features of the task patterns within defined dimensions. Consequently, offline task scheduling among edge computing-enabled entities is performed on the set of all SOM neurons using the Hungarian method to determine the expected optimal task assignments. In real-time context, whenever a task arrives at the infrastructure, the expected optimal assignment for the task is scheduled to the appropriate edge computing-enabled entity. Numerical simulation results show that the proposed PIOTS mechanism overcomes existing solutions in terms of computation performance and service capability.<\/jats:p>","DOI":"10.1155\/2018\/2101206","type":"journal-article","created":{"date-parts":[[2018,4,4]],"date-time":"2018-04-04T23:30:34Z","timestamp":1522884634000},"page":"1-9","source":"Crossref","is-referenced-by-count":15,"title":["Pattern-Identified Online Task Scheduling in Multitier Edge Computing for Industrial IoT Services"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"http:\/\/orcid.org\/0000-0003-1565-4376","authenticated-orcid":true,"given":"Nhu-Ngoc","family":"Dao","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Chung-Ang University, Seoul 06974, Republic of Korea"}]},{"given":"Duc-Nghia","family":"Vu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Chung-Ang University, Seoul 06974, Republic of Korea"}]},{"given":"Yunseong","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Chung-Ang University, Seoul 06974, Republic of Korea"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-1879-688X","authenticated-orcid":true,"given":"Sungrae","family":"Cho","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Chung-Ang University, Seoul 06974, Republic of Korea"}]},{"given":"Chihyun","family":"Cho","sequence":"additional","affiliation":[{"name":"Samsung Research, Samsung Electronics Co., Ltd., Seoul 06765, Republic of Korea"}]},{"given":"Hyunbum","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of North Carolina at Wilmington, Wilmington, NC 28403, USA"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/mcc.2016.91"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/access.2017.2777443"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.neunet.2012.09.018"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s10723-015-9359-2"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2017.2682318"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2017.2717482"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/3961689"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/access.2017.2712138"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/jsac.2016.2611964"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/tpds.2016.2582160"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2016.2633522"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/tsusc.2017.2706620"},{"key":"16","year":"2017","journal-title":"Mobile Information Systems"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpdc.2014.09.002"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/5087525"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2017.04.016"},{"key":"22","year":"2013"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2018\/2101206.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2018\/2101206.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2018\/2101206.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,4,5]],"date-time":"2018-04-05T23:08:18Z","timestamp":1522969698000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2018\/2101206\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":17,"alternative-id":["2101206","2101206"],"URL":"https:\/\/doi.org\/10.1155\/2018\/2101206","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"value":"1574-017X","type":"print"},{"value":"1875-905X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018]]}}}
