基于近似投影校正的无线传感器网络三维定位机制
The 3D Localization Mechanism for Wireless Sensor Networks Based on Approximate Projection Correction
摘要
Abstract
This paper presents a non-dimensional distance wireless sensor network localization algorithm based on approximate projection correction for the problem that the localization error is large. The results which get by using the least squares method is approximate projected as close as possible to the surface of the mountain which full use of existing terrain features,greatly reducing the location error. In the two-dimensional Gaussian distribution density function simulation scenarios,the relative localization error is about 35%,dramatically increased the accuracy of lo-cation and it have high practical value.关键词
