Proximity-Based Location with Robustness to Byzantine Failures

As more short-range communication devices, such as devices equipped with Bluetooth or WiFi are more commonly found within environment that suffer from NLOS or urban canyons, these devices can become part of a collaborative network to develop a sophisticated high-accuracy positioning solution. One such service is the proximity-based service (PBS), which utilizes a proximity-based positioning solution. In an ideal environment, the system can provide highly accurate estimates. However, in practical applications, the presence of outlier users decreases the accuracy of the estimates produced by the proximity-based positioning solution. Therefore, a robust proximity-based positioning solution is proposed to address this concern and improve the positioning accuracy of the PBS.
