基于GDOP加权的TOA/AOA混合定位算法
Hybrid TOA/AOA Positioning Algorithm Based on GDOP Weighting
摘要
Abstract
Existing Time of Arrival/Angle of Arrival(TOA/AOA) positioning algorithms based on Wireless Sensor Network(WSN) have low accuracy under the condition that the position of Anchor Nodes(AN) has error.Fusing Geometric Dilution of Precision(GDOP) weighting,an improved hybrid TOA/AOA positioning algorithm is proposed in this paper.According to the measurement error of positioning parameters from the ANs and its position error,GDOP calculation formula is derived for TOA/AOA positioning algorithm which is based on single AN.According to the measurement error of all ANs and the relationship between BN and ANs in the WSN,the GDOP formula is derived based on weighting fusion algorithm.Simulation results show that positioning accuracy of the improved algorithm is higher than that of the positioning algorithm based on mean weighting.关键词
