Existing RFID localization approaches rely\n          on signal strength to measure the distance between RFID reader and tags. However, because\n          of the environmental complexity and inferences, the measurement of distance by signal\n          strength is not accurate, which causes large error in localization. In this paper we\n          develop a novel algorithm to improve the RFID localization accuracy. Our algorithm is\n          based on particle swarm optimization. More importantly, we add reference tags in the\n          deployment, and design a parameter named Correction Factor in PSO to measure the distances\n          more accurately by signal strength. The result shows that compared with the previous\n          method without the correction factor, our proposed approach can increase the accuracy by\n          50%. This method has good application prospect in equipment management.<\/jats:p>","DOI":"10.3233\/jifs-169109","type":"journal-article","created":{"date-parts":[[2016,10,14]],"date-time":"2016-10-14T10:32:13Z","timestamp":1476441133000},"page":"2697-2706","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["Accurate RFID localization algorithm with\u00a0particle swarm optimization based          on\u00a0reference tags"],"prefix":"10.1177","volume":"31","author":[{"given":"Jian-qiang","family":"Li","sequence":"first","affiliation":[{"name":"College of Computer Science and Software Engineering,\r            Shenzhen University, Shenzhen, China"}]},{"given":"Shen-peng","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Computer Science and Software Engineering,\r            Shenzhen University, Shenzhen, China"}]},{"given":"Lei","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Computing, The Hong Kong Polytechnic University"}]},{"given":"Xiang-hua","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Computing, The Hong Kong Polytechnic University"}]},{"given":"Zhong","family":"Ming","sequence":"additional","affiliation":[{"name":"College of Computer Science and Software Engineering,\r            Shenzhen University, Shenzhen, China"}]},{"given":"Gang","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Computer Science and Software Engineering,\r            Shenzhen University, Shenzhen, China"}]}],"member":"179","published-online":{"date-parts":[[2016,11]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1023\/B:WINE.0000044029.06344.dd"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/INFCOM.2013.6567119"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/INFCOM.2012.6195606"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCN.2004.136"},{"key":"e_1_3_2_6_2","first-page":"54","article-title":"An indoors wireless positioning system based on wireless local area\n            network infrastructure","author":"Wang Y.","unstructured":"WangY., JiaX. and LeeH.K., An indoors wireless positioning system based on wireless local area network infrastructure, 6th Int Symp on Satellite Navigation Technology Including Mobile Positioning & Location Services, 54.","journal-title":"6th Int Symp on Satellite Navigation Technology Including Mobile Positioning & Location Services"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/ICC.2010.5502809"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/RFID.2010.5467253"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/RFID.2010.5467268"},{"key":"e_1_3_2_10_2","unstructured":"HightowerJ.
