| Title | BLE-based localization using Energy-Based Ratio and Maximum Likelihood Estimation |
| Summary | The project proposes a BLE-based Wireless Sensor Network for indoor localization, where BLE beacons act as anchor nodes and a mobile phone serves as the sink node. RSSI values from the anchors are processed to perform live tracking of the mobile device. Two algorithms are implemented and compared: Energy-Based Ratio (EBR) and Maximum Likelihood Estimation (MLE). The algorithms are first simulated in MATLAB, then integrated into a mobile application built in Android Studio for real-time demonstration and visualization. Experiments are conducted under Line-of-Sight (LOS) conditions to provide a clean comparison of the two methods, with MATLAB analysis of logged data providing systematic evaluation and comparison of EBR and MLE accuracy. |
