中文摘要：
节点定位在无线传感器网络的应用中起着重要作用,一直备受学术界和工业界的关注。现有的大多数定位算法针对平面应用而设计,无法满足三维空间应用。针对目前三维空间定位算法的不足,提出了一种新型的无线传感器网络三维定位机制（BTDL）,算法中根据未知节点通信范围内锚节点数目,建立空间向量模型进行定位。仿真结果表明,该算法不仅提高了节点定位精度,并且锚节点通信半径和密度对算法的定位误差影响较小。
英文摘要：
Node localization is crucial to wireless sensor network and has been paid much attention to both academia and industry all the times.Existing localization methods are not suitable for three-dimensional terrains due to their design for planar applications.According to the shortage of some existing algorithms proposed for 3D,in this paper a novel three-dimensional localization scheme in wireless sensor network（BTDL） is proposed.This scheme establishes a vector space model based on the number of the anchor nodes from the communication range of unknown node.The simulation results demonstrate that the algorithm is of great advantages in improving location accuracy,radius of communication and density of anchor nodes have little effect on position error.
