An Improved Dynamic Prediction Fingerprint Localization Algorithm Based On KNN
Because there are some problems in WiFi indoor positioning system such as low positioning accuracy and instability positioning results,the paper deeply studied KNN fingerprint localization algorithm and improved the algorithm according to the characteristics of signal propagation volatile in the indoor environment.The algorithm finds the nearest neighbor through dynamically predicting node position and filtering out the RP without similarity RSS vector at labels from wireless map in order to reduce time and computational complexity of the algorithm KNN.The experimental results show that the improved algorithm has been greatly improved in terms of location accuracy.
