| 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。

| Abstract: | 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 nod... |
