KNN/FCM HYBRID MEHOD USING GATH-GEVA METHOD FOR INDOOR LOCATION DETERMINATION IN WALN

摘要

PURPOSE: A wireless indoor measuring method based on FCM grouping through a KNN and a GG method is provided to increase database searching efficiency of an indoor measuring determination. CONSTITUTION: RPs(Reference Points) having a first propagation characteristic value closed to a second propagation feature value is selected in a KNN(K-Nearest Neighbor) method(S120). The first propagation characteristic value data forms a group in an FCM(Fuzzy C-Means) method(S130). A GG distance about the first propagation characteristic value data and a group center vector is selected(S140). A location of the terminal is estimated by calculation of average of a location coordinate(S150).
