However, the instability of Bluetooth RSSI (Received Signal Strength Indicator) promotes a huge challenge in localization accuracy. To improve the localization accuracy, this paper measures the distance of RSSI vectors on their low-dimensional manifold and proposes a novel positioning method IWKNN (Isomap-based Weighted <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>K<\/mml:mi><\/mml:mrow><\/mml:math>-Nearest Neighbor). The proposed method firstly uses Isomap to generate low-dimensional embedding for RSSI vectors. Then, the distance of two given RSSI vectors is measured by Euclidean distance of their low-dimensional embeddings. Finally, the position is calculated by WKNN. Experiment indicates that the proposed approach is more robust and accurate.<\/jats:p>","DOI":"10.1155\/2016\/8765874","type":"journal-article","created":{"date-parts":[[2016,11,30]],"date-time":"2016-11-30T16:05:23Z","timestamp":1480521923000},"page":"1-11","source":"Crossref","is-referenced-by-count":9,"title":["IWKNN: An Effective Bluetooth Positioning Method Based on Isomap and WKNN"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8023-8435","authenticated-orcid":true,"given":"Qi","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Mathematics, Northeastern University, Shenyang, Liaoning Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingying","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Northeastern University, Shenyang, Liaoning Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangde","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Northeastern University, Shenyang, Liaoning Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanrui","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Northeastern University, Shenyang, Liaoning Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9907-3741","authenticated-orcid":true,"given":"Xiaojun","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Northeastern University, Shenyang, Liaoning Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/tgis.12102"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2013.01.006"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmcj.2011.09.003"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2015.2430281"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/862347"},{"year":"2016","key":"20"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.4156\/aiss.vol5.issue1.8"},{"year":"2005","key":"26"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1126\/science.290.5500.2323"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1126\/science.290.5500.2319"},{"year":"1995","key":"29"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/8765874.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/8765874.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2016\/8765874.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,11,30]],"date-time":"2016-11-30T16:05:24Z","timestamp":1480521924000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2016\/8765874\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":11,"alternative-id":["8765874","8765874"],"URL":"https:\/\/doi.org\/10.1155\/2016\/8765874","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2016]]}}}
