改进蛇优化算法在室内UWB定位的应用
Application of Improved Snake Optimization Algorithm in Indoor UWB Positioning
摘要
Abstract
To meet the need of indoor positioning in recent years and increase the overall positioning accuracy,a Ultra-Wide Band(UWB)indoor positioning technology based on a Snake Optimization(SO)with sine chaotic mapping and sine cosine optimization is proposed,which is combined with an adaptive measuring value adjustment strategy and takes the ranging values as parameters of SO's fitness function.SO is a new metaheuristic and intelligent algorithm which imitates the foraging behavior and mating behavior of snake.To improve optimization ability of the algorithm,the chaotic map is introduced into the population initialization of SO to increase individuals'diversity.After location updating of males and females,combine the updated locations with Sine and Cosine Algorithm(SCA)to coordinate global exploration and local exploration.The experiment results show that under the indoor environment,the method can increase positioning accuracy effectively and its performance is good.Compared to other traditional intelligent algorithms,the positioning accuracy and convergence efficiency of improved SO algorithm has significant improvement.关键词
