摘要 文章研究了基于DV-HOP的定位算法,并分析了算法产生误差的原因。为了提高定位精度,针对DV-HOP的一种经典改进算法LPC,文中对影响定位精度的三个重要参数:锚节点数目、节点数目、节点通信半径,进行了研究并对参数进一步优化。理论分析和仿真结果表明:经参数优化后,算法的定位精度得到了有效的提高。 This paper is researched on localization algorithm based on DV-HOP, and the reason of postion error is analyzed. For a clas- sic improved algorithm LPC based on DV HOP, three parameters including the number of anchors, the number of nodes, node communica- tion radius which affect positioning accuracy are studied and further optimized. Theoretical analysis and simulation results show that： after the parameter optimization, positioning accuracy of the algorithm is effectively improved.
