Abstract:	摘要： Location information is crucial for many applications in wireless sensor networks. Many types of localization algorithms have been proposed in the literature. Off-shelf sensors equipped with no specialized hardware are inexpensive and have made range-free localization schemes the most practical, especially in a large-scale sensor network. However, the range-free schemes have seldom considered the impact of the local neighborhood, the number of neighbors, or estimation of the communication hop distance of a node. In this paper, we use the local neighborhood to define the communication hop distance, called the single hop size (SHS), of a node. In addition, we propose a novel correction scheme, called SCS (SHS correction scheme), for multi-hop range-free localization. Compared to other range-free methods, SCS significantly reduces errors in position determination, even when the number of anchor nodes is low. 出版者：社團法人中華民國計算語言學學會出版日期： 2015-05-01 出處： Journal of Information Science and Engineering, 2015-05, Vol.31 (3), p.879-896 資源來源：華藝CEPS中文電子期刊服務識別號： ISSN: 1016-2364 識別號： DOI: 10.6688/JISE.2015.31.3.7
