Indoor localization using K-nearest neighbor and artificial neural network back propagation algorithms

Currently, indoor localization plays vigorous role in academia and industries. In the proposed technique, 99.78% of room level classifications are correctly classified using K-nearest Neighbor (KNN). For regression based problem, an Artificial Neural Network in Back Propagation (ANNBP) performs an accuracy of 50% and 100% for errors less than 0.5 m and 0.9 m respectively. The root-mean-square error (RMSE) for regression based localization is 0.56. Thus, the result confirmations that the integration of KNN with ANNBP techniques can give better indoor location based services (LBSs).
