A Novel Single Anchor Localization Method for Wireless Sensors in 5G Satellite-Terrestrial Network

Satellites extend the 5G Internet of Things (IoT) applications to remote areas by providing global coverage. In applications like environmental and wildlife monitoring, the location information of IoT sensors is equally important as the data itself. This location information can also be utilized for spectrum management between the satellite and IoT networks. The localization is performed using nodes with known positions called anchor nodes (ANs). Optimization analysis of ANs significantly enhance the localization performance. In this paper, we propose a single AN-based localization algorithm for wireless sensors. The proposed localization approach uses directional information and mobility, focusing on finding the shortest path with only two beacon points. Simulation results demonstrate the superiority of the proposed localization algorithm over the state of the art approaches.
