中文摘要：

将无线传感器网络中二维定位扩展到三维定位,并针对三维空间定位精度低的问题,分别提出了基于距离函数和指数函数的三维加权质心定位算法。仿真结果表明：基于这两种函数的加权定位算法的精度较传统三维质心算法有了显著提高,平均定位误差均降低了8%。同时,在锚节点比例为15%时其网络覆盖率可达92%以上。

英文摘要：

Three-dimension（3D） weighted centroid algorithm is extended from two-dimension（2D） space.A novel weighted centroid location algorithm based on distance function and index function is proposed respectively,to improve localization precision of the traditional 3D centroid algorithm.Simulation result shows the two new algorithms improve localization precision obviously.The average localization error decrease by 8%,and the network coverage rate reaches above 92 % at 15 % ratio of anchor node.
