Recently, crowdsourced Wi-Fi fingerprint attracts much attention, which leads to a self-organized localization system avoiding painful survey efforts. However, this participatory approach introduces new challenges with no previously proposed techniques such as heterogeneous devices, short measurement time, and multiple values for a single position. This paper proposes an efficient localization method combating the three major technical issues in the crowdsourcing based systems. We evaluate our indoor positioning method using 5 places with different radio environment and 8 different mobile phones. The experimental results show that the proposed approach provides consistent localization accuracy and outperforms existing localization algorithms.<\/jats:p>","DOI":"10.1155\/2016\/4916563","type":"journal-article","created":{"date-parts":[[2016,8,21]],"date-time":"2016-08-21T17:01:15Z","timestamp":1471798875000},"page":"1-18","source":"Crossref","is-referenced-by-count":11,"title":["Crowdsource Based Indoor Localization by Uncalibrated Heterogeneous Wi-Fi Devices"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0955-3421","authenticated-orcid":true,"given":"Wooseong","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, Gachon University, 1342 Seongnam-ro, Gyeonggi 461701, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3296-9783","authenticated-orcid":true,"given":"Sungwon","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of California, Los Angeles, Los Angeles, CA 90095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Gerla","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of California, Los Angeles, Los Angeles, CA 90095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6393-5757","authenticated-orcid":true,"given":"Eun-Kyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Information and Telecommunication Engineering, Incheon National University, 119 Academy-ro, Yeonsu-gu, Incheon 406772, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","first-page":"78","year":"2008","journal-title":"Electronics"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.5120\/2946-3928"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2009.090103"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCC.2007.905750"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1145\/128756.128759"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/11428572_8"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2015.03.001"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/tpds.2012.179"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/tmc.2011.243"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-04385-7_6"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2008.070373"},{"key":"33","doi-asserted-by":"publisher","DOI":"10.1007\/s11036-008-0139-0"},{"key":"36","year":"2001"},{"key":"37","first-page":"1","volume":"6","year":"2000","journal-title":"ACM Mobile Networks and Applications"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4916563.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4916563.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/4916563.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,21]],"date-time":"2016-08-21T17:01:17Z","timestamp":1471798877000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/misy\/2016\/4916563\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":14,"alternative-id":["4916563","4916563"],"URL":"https:\/\/doi.org\/10.1155\/2016\/4916563","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"value":"1574-017X","type":"print"},{"value":"1875-905X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
