基于接收信号强度指示加权融合的定位算法
Localization Algorithm Based on Received Signal Strength Indication Weighted Fusion
摘要
Abstract
Based on the received signal strength indicator wireless sensor network location problem, the article puts forward an improved Kalman filtering method to obtain the evaluated distance between label and nodes through eliminating the non-line-of-sight error in the ranging process. Then, three effects on location accuracy are analysed, which are the distance between label and node, the quality of location unit and the position of label and an improved trilateral localization algorithm is proposed, in which weighted fusion of some position coordinates calculated by the filtered distance. Finally, the simulation is given to demonstrate the effectiveness of the proposed algorithm.关键词
