Abstract: In view of problem of low efficiency of traditional sampling of RSS fingerprint data point by point in underground roadway, a rapid generation method of RSS fingerprint data based on Kriging interpolation algorithm was proposed. Firstly, theory variogram is obtained by fitting experiment variogram with RSS fingerprint data of a few observation points. Then weight coefficient of Kriging interpolation algorithm is gotten under the condition of unbiased estimation and the minimum estimation variance. Finally, RSS fingerprint data of estimation points are calculated through Kriging interpolation algorithm. The experimental result shows that the RSS fingerprint data obtained by the method are accurate and location error is low.
