2-Step robust DNN model for RSSI-based indoor localization

抄録

In this paper, we introduce a novel approach called the 2-Step Robust Deep Neural Network (DNN), designed specifically for indoor localization utilizing received signal strength indicator (RSSI) data. This method represents an advancement over the previously proposed 2-Step Extreme Gradient Boosting (XGBoost), aiming to enhance estimation precision by leveraging a single coordinate (x or y) as a feature. The pivotal alterations involve transitioning from XGBoost to DNN and refining the training data to develop a resilient learning model for positional coordinates. Through comprehensive simulations, we demonstrate that the proposed 2-Step Robust DNN attains superior estimation accuracy while preserving the absence of constraints on the dataset.
