A weighted centroid localization algorithm based on received signal strength indicator (RSSI) was proposed for underground mine disaster monitoring system which based on wireless sensor network (WSN).It firstly accessed to the path of decline index dynamicallyand then calculated its own location by weighted centroid algorithm.When it accessed to the path of decline index dynamicallypath loss exponent was calculated in location areas which accurately reflects the affect of the signal fading in different tunnel areas and enhances adaptive capacity to the environment of distance detection algorithm.Weighted centroid algorithm embodies the impact of each reference node to the centroid coordinate by weighted coefficientswhich improves the accuracy of personnel localization.The experimental results show that the proposed algorithm achieves better positioning accuracy with simple calculation and processwhich demonstrates it is suitable for coal mine environment.
