基于四面体模型的三维加权质心定位算法
Three-dimensional Weighed Centroid Localization Algorithm Based on Tetrahedral Model
摘要
Abstract
In order to solve the problem of locating unknown nodes in three-dimensional space, this paper proposes a three-dimensional weighed centroid localization algorithm based on tetrahedral model. The tetrahedron consists of four anchor nodes. The unknown nodes are located according to the distances between unknown nodes and anchor nodes, which are weighted sum. It uses the data information of Received Signal Strength Indicator(RSSI) to revise weighting factor. Simulation results show that the localization accuracy of the algorithm is high.关键词
