Abstract：A novel three-phase localization method for coal mine wireless sensor networks is presented based on LQI and Takane's non-metric MDS.To address the problems brought by severe natural conditions of coal mine,the whole localization process is divided into three pha-ses:regional localization,multi-dimensional scaling and precise localization.By fusing the lo-calization data,an accurate position coordinate of moving targets under coal mine is obtained e-ventually. We set up a ZigBee network and conduct our experiments in a real air-raid shelter tunnel to simulate coal mine environment.The experimental results show that the localization error of the metric MDS algorithm is less than that of metric MDS algorithms.The three-phase localization method solves the low localization accuracy problems which caused by harsh vapors and the complex geological structure in coal mine.
