In this algorithm, the energy heterogeneity of the nodes is fully reflected in the mechanism of cluster-heads\u2019 election. It optimizes the competition radius of the cluster-heads according to the residual energy of the nodes. This kind of uneven clustering prolongs the lifetime of the cluster-heads with lower residual energies or near the sink nodes. In data transmission stage, the hybrid multihop transmission mode is adopted, and the next-hop routing election fully takes account of the factors of residual energies and the distances among the nodes. The simulation results show that the introduction of an uneven clustering mechanism and the optimization of competition radius of the cluster-heads significantly prolonged the lifetime of the network and improved the efficiency of data transmission.<\/jats:p>","DOI":"10.1155\/2016\/7542907","type":"journal-article","created":{"date-parts":[[2016,9,18]],"date-time":"2016-09-18T17:01:52Z","timestamp":1474218112000},"page":"1-9","source":"Crossref","is-referenced-by-count":5,"title":["Routing Algorithm with Uneven Clustering for Energy Heterogeneous Wireless Sensor Networks"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1843-0522","authenticated-orcid":true,"given":"Ying","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Information Engineering, Shanghai Maritime University, Shanghai 201306, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6581-4134","authenticated-orcid":true,"given":"Wei","family":"Xiong","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Shanghai Maritime University, Shanghai 201306, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8861-5461","authenticated-orcid":true,"given":"Dezhi","family":"Han","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Shanghai Maritime University, Shanghai 201306, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1709-1191","authenticated-orcid":true,"given":"Wei","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Tennessee State University, Nashville, TN 37209, USA"}]},{"given":"Jun","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Information Engineering, Shanghai Maritime University, Shanghai 201306, China"},{"name":"Department of Electrical and Computer Engineering, University of Central Florida, Orlando, FL 32816, USA"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2007.05.024"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.procs.2015.03.133"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1145\/2479957.2479961"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/jsen.2015.2437904"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.3390\/s150203625"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2015.2412917"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.procs.2015.12.161"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2009.03.008"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2014.07.019"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/s10776-016-0304-5"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2012.12.001"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/tmc.2004.41"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/j.asoc.2011.04.007"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2011.05.002"},{"year":"2004","key":"22"},{"issue":"3","key":"23","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1360\/jos170481","volume":"17","year":"2006","journal-title":"Journal of Software"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.3724\/sp.j.1016.2009.02393"},{"issue":"3","key":"25","first-page":"392","volume":"45","year":"2008","journal-title":"Journal of Computer Research and Development"},{"issue":"2","key":"26","first-page":"57","volume":"28","year":"2009","journal-title":"Transactions of Shenyang Ligong University"},{"issue":"1","key":"27","first-page":"27","volume":"30","year":"2007","journal-title":"Chinese Journal of Computers"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2016\/7542907.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2016\/7542907.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2016\/7542907.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,24]],"date-time":"2017-06-24T19:05:57Z","timestamp":1498331157000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2016\/7542907\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":20,"alternative-id":["7542907","7542907"],"URL":"https:\/\/doi.org\/10.1155\/2016\/7542907","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2016]]}}}
