The RSSI value fluctuates heavily due to the poor environment of coal mine underground. The nodes with larger RSSI value corrected by Gaussian-weighted model were selected as beacon nodes. In order to reduce the positioning error further, the estimated positions of the locomotives were corrected by the weighted distance correction method. The difference between actual position and estimated position of beacon node was regarded as the positioning error and was given a corresponding weight. The results of simulation show that the positioning accuracy of Gaussian-weighted model is better than statistical average model and Gaussian model and it has a high positioning accuracy after correcting positioning error correction. In the 10\u2009m of communication range, positioning error can be maintained at 0.5\u2009m.<\/jats:p>","DOI":"10.1155\/2015\/918962","type":"journal-article","created":{"date-parts":[[2015,2,17]],"date-time":"2015-02-17T16:03:12Z","timestamp":1424188992000},"page":"1-8","source":"Crossref","is-referenced-by-count":14,"title":["Improved RSSI Positioning Algorithm for Coal Mine Underground Locomotive"],"prefix":"10.1155","volume":"2015","author":[{"given":"Bin","family":"Ge","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Anhui University of Science & Technology, Huainan, Anhui 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Anhui University of Science & Technology, Huainan, Anhui 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianghong","family":"Han","sequence":"additional","affiliation":[{"name":"School of Computer and Information, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bao","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Anhui University of Science & Technology, Huainan, Anhui 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2012.2189731"},{"issue":"3","key":"2","first-page":"109","volume":"28","year":"2013","journal-title":"Geography and Geo-Information Science"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.tust.2011.08.007"},{"issue":"5","key":"4","first-page":"782","volume":"34","year":"2012","journal-title":"Piezoelectrics and Acoustooptics"},{"issue":"8","key":"5","first-page":"1362","volume":"38","year":"2013","journal-title":"Journal of the China Coal Society"},{"issue":"3","key":"6","first-page":"522","volume":"38","year":"2013","journal-title":"Journal of the China Coal Society"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.sna.2011.08.015"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2011.03.019"},{"issue":"1","key":"9","first-page":"178","volume":"35","year":"2014","journal-title":"Chinese Journal of Scientific Instrument"},{"issue":"2","key":"10","first-page":"285","volume":"22","year":"2009","journal-title":"Chinese Journal of Sensors and Actuators"},{"issue":"11","key":"11","first-page":"4156","volume":"29","year":"2012","journal-title":"Application Research of Computers"},{"issue":"5","key":"12","first-page":"647","volume":"31","year":"2010","journal-title":"Journal of Northeastern University"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.3969\/j.issn.1004-1699.2012.12.025"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.proeng.2011.08.162"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2012.08.002"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.aei.2010.09.003"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/918962.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/918962.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/918962.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,19]],"date-time":"2016-08-19T01:57:06Z","timestamp":1471571826000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2015\/918962\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":16,"alternative-id":["918962","918962"],"URL":"https:\/\/doi.org\/10.1155\/2015\/918962","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"type":"print","value":"2090-0147"},{"type":"electronic","value":"2090-0155"}],"subject":[],"published":{"date-parts":[[2015]]}}}
