基于四面体模型RSSI的优化加权质心定位算法
An Optimal Weighted Centroid Localization Algorithm Based on RSSI Tetrahedron Model
摘要
Abstract
Aiming at the problem that RSSI ranging technology is in low precision locating node location,a weighted centroid localization algorithm is presented.First by RSSI ranging and combining tetrahedron model,traditional weighted centroid localiza-tion algorithm is used to calculate multiple nodes to estimate position.Then optimization weights weighted centroid is reoccupied to solve the multiple estimated position and finally the node position is determined.The simulation results show that compared with the traditional weighted centroid algorithm,the algorithm given positioning precision is improved by 5.89%.关键词
