To alleviate these problems, we design a distributed group location update algorithm (DGLU) in which geographically proximate IoT devices determine whether to conduct the location update in a distributed manner. To maximize the accuracy of the locations of IoT devices while maintaining a sufficiently small energy outage probability, we formulate a constrained stochastic game model. We then introduce a best response dynamics-based algorithm to obtain a multi-policy constrained Nash equilibrium. From the evaluation results, it is demonstrated that DGLU can achieve an accuracy of location information that is comparable with that of the individual location update scheme, with a sufficiently small energy outage probability.<\/jats:p>","DOI":"10.3390\/s20247336","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T09:41:41Z","timestamp":1608543701000},"page":"7336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Distributed Group Location Update Algorithm for Massive Machine Type Communication"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4169-6804","authenticated-orcid":false,"given":"Mincheol","family":"Paik","sequence":"first","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9067-445X","authenticated-orcid":false,"given":"Haneul","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,21]]},"reference":[{"key":"ref_1","unstructured":"(2020, February 27).
