Location algorithm of fingerprint database based on minimum value for multi-mapping data structure

GUO Xingang;HU Lang;School of Computer Science & Engineering,Changchun University of Technology;  
Multi-mapping data structure is applied to build fingerprint database at off-line phase to make every sampling point match the RSSI information value of the same AP.While at online matching stage,Euclidean distance between the RSSI information of the undetermined site and the fingerprint information of the off-line database is calculated.The smaller the Euclidean distance value,the higher the fitting degree,which indicates that the minimum value of the fitting degree can be obtained.Fingerprint points associated with undetermined sites can be identified accordingly.Finally,WKNN matching algorithm is used to calculate the estimated coordinates of undetermined sites.
