In allusion to the special environment of coal mine roadways, the strategy laying anchor nodes evenly on the left and right sides and the top of roadways in accordance with the oblique triangle and the mine personnel positioning algorithm based on received and transmitted signal strength of nodes were adopted in the paper. The algorithm estimating the distance between an unknown node and an anchor node through built-in received and transmitted signal strength information of the anchor node could realize the mine personnel positioning with only two anchor nodes. Both theoretical analysis and simulation experiments show that it improves the personnel positioning accuracy in the coal mine roadway environment effectively used the effective combination of the nodes arrangement strategy and the positioning algorithm proposed in the paper. ? 2014 NSP Natural Sciences Publishing Cor.
