摘要 节点定位是无线传感器网络应用的关键技术之一。为了提高无线传感器网络节点定位的精确度,文章分析了质心定位算法的原理和优缺点,提出一种基于复合权值的质心定位改进算法(简称为RWCLA),利用不同的权值来体现不同的锚节点对多边形质心计算结果的影响。仿真实验表明,改进后的算法比标准质心定位算法的定位精度有了明显的提高。 Localization of nodes is the one of key technologies for application of wireless sensor network.To improve the precision of node localization,this study analyzed the principles,advantages and disadvantages of the centroid localization algorithm.A kind of improved centroid localization algorithm based on recombination weight is stated.The influence of anchors on the result of polygon centrorid calculation can be reflected by the corresponding weight.The simulation results showed that the improved algorithm had a better performance than the standardized centroid localization algorithm in localization accuracy.
