一种自适应智能三边定位算法的设计与实现
Design and Implementation of Adaptive Intelligent Trilateral Localization Algorithm
摘要
Abstract
In order to effectively restrain the influence of indoor complex environment on the wireless sensor network nodes localization accuracy,and reduce the dependence of the indoor positioning system on the environment,a new adaptive intelligent trilateral localization algorithm is proposed.By measuring the fluctuation of the distance between the mobile node and the beacon nodes,the algorithm generates the corresponding adaptive factor.The variation factor controls the fine tuning of the distance radius in the trilateral localization algorithm,which makes the area of the overlapping part of the three positioning circles smaller than a certain precision.Then the maximum inscribed circle in the overlap region is plotted,and regards the center of the circle as the location of the mobile node.The simulation results show that the proposed algorithm has higher localization accuracy and better robustness than the weighted trilateral localization algorithm,and can adapt to different sizes and types of localization systems.关键词
