AN IMPROVED NEAREST NEIGHBORS (INN) ALGORITHM FOR ACCURATE WIFI BASED INDOOR POSITIONING

This work aims to enhance the accuracy of location estimation in indoor environment, using the radio frequency (RF) wireless technology. A modified version of the Nearest Neighbors (NN) algorithm, named Improved NN (INN), is proposed. The performance of this algorithm is compared experimentally to that of many other powerful methods. The comparison shows the effectiveness of the proposed method.
