摘要
Abstract
In order to overcome the problem of anisotropy due to non line of sight,density and other causes, a multihop range-free localization method based on kernel Tikhonov regularization is presented. This method constructs a mapping function by kernel Tikhonov regularization between hop-counts and physical distances for pairs of anchors, and obtain the no-anchors to anchors estimated distance using the measurement of hop-counts. The theoretical analysis and simulation results show that the improved method can solve the ill-condition problem and improve the positioning accuracy with avoiding the influence of anisotropy,and has the less calculation cost and parameters,being suitable for the harsh nodes deployment environment with high practical value.关键词
