Abstract: After describing algorithm for indoor positioning based on dynamic K value and weighted localization (EWKNN),this article put forward an improved indoor localization algorithm based on AP MAC address match.First of all,EWKNN is used to dynamically choose reference points.Then according to the AP MAC matching degree bet-ween reference points and test point,further optimal positioning reference points are determined.Finally the weighted positioning is obtained in terms of signal distance between optimal reference points and test point.Experimental studies indicate that the improved algorithm has better performance at positioning accuracy comparing with EWKNN localization algorithm.
