基于平面投影的三维空间定位算法
Three-dimensional Space Positioning Algorithm Based on Planar Projection
摘要
Abstract
In the process of Wireless Sensor Network(WSN)node positioning,it is more important to improve the x-axis and y-axis positioning accuracy of an unknown node than z-axis positioning accuracy,so this paper proposes a positioning algorithm based on planar projection on the basis of RSSI Gaussian Mixed(RGM)algorithm.It improves unknown node positioning accuracy on the x-axis and y-axis directions by reducing the projected area of spatial positioning error region.Simulation results show that,compared with RGM algorithm,the proposed algorithm can improve the x-axis and y-axis positioning accuracy without any inscrease in time complexity and network traffic.关键词
