摘要
节点定位作为无线传感器网络应用支撑技术之一,一直倍受学术界和工业界的关注。现有的定位算法大多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,在三边测距定位基础上,本文以三维空间四边测量法为基础,提出了三维空间二次定位法,并对其性能进行了分析,给出了算法的定位误差。
As one supporting technology of wireless sensor network applications, node localization has been paid much attention to both academia and industry all the times. Existing localization methods are not suitable for 3-dimensional（3D） terrains, due to their design for planar applications. According to the shortage of some existing algorithms for 3D, the re-location for 3D terrain based on trilateral localization algorithm is presented, its performance is analyzed and its localization error is also calculated in this paper.
