Since the range-free scheme is based on the topology information, the accuracy of distance estimation is considerably affected by node density or node deployment. In this paper, we propose a geometric range-free localization algorithm which estimates the unknown positions geometrically by topological information without considering the distance estimation. To achieve this, we propose an optimal anchor node selection algorithm which selects the anchor nodes connected topologically well for the geometrical location estimation. Simulation results show that the proposed algorithm offers considerably an improved performance compared to the other existing studies. <\/jats:p>","DOI":"10.1155\/2014\/509892","type":"journal-article","created":{"date-parts":[[2014,4,10]],"date-time":"2014-04-10T21:02:45Z","timestamp":1397163765000},"page":"509892","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Geometric Range-Free Localization Algorithm Based on Optimal Anchor Node Selection in Wireless Sensor Networks"],"prefix":"10.1177","volume":"10","author":[{"given":"Hyunjae","family":"Woo","sequence":"first","affiliation":[{"name":"Ajou University, 206 World cup-ro, Yeongtong-gu, Suwon, Gyeonggi-do 443-749, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaewoo","family":"Lee","sequence":"additional","affiliation":[{"name":"Ajou University, 206 World cup-ro, Yeongtong-gu, Suwon, Gyeonggi-do 443-749, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,4,10]]},"reference":[{"key":"B1-2014-509892","doi-asserted-by":"publisher","DOI":"10.1145\/953460.953490"},{"key":"B2-2014-509892","first-page":"81","volume-title":"Proceedings of the 9th Annual International Conference on Mobile Computing and Networking (MobiCom \u203203)","author":"He T."},{"key":"B3-2014-509892","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-1286(03)00356-6"},{"key":"B4-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/GLOCOM.2001.965964"},{"key":"B5-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/TPDS.2008.239"},{"key":"B6-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/ICOIN.2013.6496697"},{"key":"B7-2014-509892","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/507605"},{"key":"B8-2014-509892","doi-asserted-by":"publisher","DOI":"10.1186\/1687-1499-2012-152"},{"key":"B9-2014-509892","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/213980"},{"key":"B10-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/MAHSS.2004.1392106"},{"key":"B11-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2009.100"},{"key":"B12-2014-509892","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2010.129"},{"key":"B13-2014-509892","first-page":"618","volume-title":"Proceedings of the International Conference on Information Networking (ICOIN \u203213)","author":"Woo H."}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/509892","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2014\/509892","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/509892","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,16]],"date-time":"2021-05-16T13:07:05Z","timestamp":1621170425000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1155\/2014\/509892"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,4,1]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2014,4,1]]}},"alternative-id":["10.1155\/2014\/509892"],"URL":"https:\/\/doi.org\/10.1155\/2014\/509892","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"value":"1550-1477","type":"print"},{"value":"1550-1477","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,4,1]]}}}
