| 摘 要： | 提出一种跳数加权质心定位算法——HWC算法。它完全基于网络连通性，采用通信跳数信息作为加权因子计算待定位节点估计位置，体现跳数不同节点对多边形质心计算结果的影响。仿真表明，该算法减小了平均定位误差，是一种适合大规模传感器网络应用的节点定位算法。

| Abstract: | This paper presents a kind of centroid locating algorithm based on hop weighted.This algorithm is based exclusively on connectivity and uses hop information as weight factor to calculate the estimated position of unknown nodes, whose hop influences the result of polygon centroid calculation.Simulations demonstrate that this algorithm can reduce the average locating errors and it is fit for mass Wireless Sensor Network(WSN) application. |

| Keywords: | Wireless Sensor Network(WSN) centroid locating algorithm improved centroid locating algorithm |
