However, due to the wireless multipath influence, the value of the received RSSI will have large fluctuations and cause large distance error when RSSI is fitted to distance. But experimental data showed that, being affected by the combined factors of the environment, the received RSSI feature vector which is formed by lots of RSSI values from different APs is a certain stability. Therefore, the paper proposed RSSI-based fingerprint feature vector algorithm which divides location area into grids, and mobile devices are localized through the similarity matching between the real-time RSSI feature vector and RSSI fingerprint database feature vectors. Test shows that the algorithm can achieve positioning accuracy up to 2\u20134 meters in a typical indoor environment. <\/jats:p>","DOI":"10.1155\/2015\/528747","type":"journal-article","created":{"date-parts":[[2015,11,1]],"date-time":"2015-11-01T21:01:49Z","timestamp":1446411709000},"page":"528747","update-policy":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Wireless Localization Based on RSSI Fingerprint Feature Vector"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0001-7699-4919","authenticated-orcid":false,"given":"Aiguo","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361024, China"}]},{"ORCID":"https:\/\/linproxy.fan.workers.dev:443\/https\/orcid.org\/0000-0003-0093-2417","authenticated-orcid":false,"given":"Ying","family":"Yuan","sequence":"additional","affiliation":[{"name":"College of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361024, China"}]},{"given":"Qunyong","family":"Wu","sequence":"additional","affiliation":[{"name":"Spatial Information Research Center of Fujian Province, Fuzhou University, Fuzhou 351002, China"}]},{"given":"Shunzhi","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361024, China"}]},{"given":"Jian","family":"Deng","sequence":"additional","affiliation":[{"name":"College of Computer and Information Engineering, Xiamen University of Technology, Xiamen 361024, China"}]}],"member":"179","published-online":{"date-parts":[[2015,11,1]]},"reference":[{"issue":"9","key":"B1-2015-528747","first-page":"1","volume":"22","author":"Cao S.","year":"2013","journal-title":"Computer Systems & Applications"},{"issue":"7","key":"B2-2015-528747","first-page":"8","volume":"43","author":"Li Z.","year":"2013","journal-title":"Radio Engineering"},{"issue":"2","key":"B3-2015-528747","first-page":"109","volume":"25","author":"Yu M.","year":"2013","journal-title":"Journal of Gansu Sciences"},{"issue":"1","key":"B4-2015-528747","first-page":"82","volume":"26","author":"Che Y.","year":"2010","journal-title":"Microcomputer Information"},{"key":"B5-2015-528747","first-page":"202","volume":"33","author":"Wang S.","year":"2011","journal-title":"Journal of Yunnan University"},{"issue":"32","key":"B6-2015-528747","first-page":"7807","volume":"8","author":"Hu B.","year":"2012","journal-title":"Computer Knowledge & Technology"},{"key":"B7-2015-528747","doi-asserted-by":"publisher","DOI":"10.13190\/jbupt.201303.91.tanzh"},{"key":"B8-2015-528747","doi-asserted-by":"publisher","DOI":"10.1109\/cnsr.2008.32"},{"key":"B9-2015-528747","first-page":"88","volume":"41","author":"Li W.","year":"2013","journal-title":"Journal of Huazhong University of Science and Technology (Nature Science)"},{"issue":"10","key":"B10-2015-528747","first-page":"72","volume":"34","author":"Lu H.","year":"2010","journal-title":"Mobile Communications"},{"issue":"4","key":"B11-2015-528747","first-page":"532","volume":"28","author":"Zhang Y.","year":"2009","journal-title":"Technical Acoustics"},{"issue":"1","key":"B12-2015-528747","first-page":"40","volume":"17","author":"Tian R.","year":"2006","journal-title":"Traditional Chinese Drug Research & Clinical Pharmacology"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/linproxy.fan.workers.dev:443\/http\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/528747","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/linproxy.fan.workers.dev:443\/http\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2015\/528747","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/linproxy.fan.workers.dev:443\/http\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/528747","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,7]],"date-time":"2021-05-07T17:36:18Z","timestamp":1620408978000},"score":1,"resource":{"primary":{"URL":"https:\/\/linproxy.fan.workers.dev:443\/http\/journals.sagepub.com\/doi\/10.1155\/2015\/528747"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,11,1]]},"references-count":12,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2015,11,1]]}},"alternative-id":["10.1155\/2015\/528747"],"URL":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1155\/2015\/528747","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"value":"1550-1477","type":"print"},{"value":"1550-1477","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,11,1]]}}}
