Energy-Efficient Clustering Scheme in Wireless Sensor Networks that Considers Sensor Node Structure Hyunduk KIM Boseon YU Wonik CHOI Heemin PARK Publication IEICE TRANSACTIONS on Communications Vol.E95-B No.8 pp.2646-2649 Publication Date: 2012/08/01 Online ISSN: 1745-1345 DOI: 10.1587/transcom.E95.B.2646 Print ISSN: 0916-8516 Type of Manuscript: LETTER Category: Network Keyword: WSN, mobile sink, clustering, HEED, split/merge, Full Text: PDF(325.5KB)>> | Errata[Uploaded on November 1,2012] Summary: We propose a novel scheme that aims to determine the optimal number of clusters based on the field conditions and the positions of mobile sink nodes. In addition, we merge algorithms of tree-based index structures to form an energy-efficient cluster structure. A performance evaluation shows that the proposed method produces highly-balanced clusters that are energy efficient and achieves up to 1.4 times higher survival rates than the previous clustering schemes, under various operational conditions. | |||||
