الملخص

Indoor localization is of paramount importance in intelligent environments, particularly in scenarios where Global Positioning System (GPS) signals are hindered by physical barriers within indoor settings. This study investigates machine learning methodologies designed to enhance the precision of indoor positioning systems. In particular, we conduct a comparative analysis of three algorithms: the conventional KNearest Neighbors (KNN), a Weighted KNN utilizing inverse distance metrics (WKNN-inv), and an additional variant that employs cosine similarity measures (WKNN-cos). Each algorithm was systematically implemented and assessed concerning its positioning accuracy. The results from simulations indicate that WKNN-inv yields an accuracy enhancement of approximately 11.2% relative to KNN, whereas WKNN-cos provides a 13.0% improvement.
