Abstract: A distributed protected wildlife tracking and monitoring system based on NBIoT is proposed to realize low power consumption, remote monitoring, customization and low cost. The key solutions including efficient power management, concurrent communication processing, and network transparent transmission are given. The system consists of trackers and a monitoring information system. Each tracker includes a NB-IoT communication and location module, a low-power microcontroller, a solar composite power supply component with lithium battery, and a high-efficiency power converter. The monitoring information system is composed of data communication equipment, server and monitoring terminals. Experiments show that the system can collect the position of wild animals remotely and display their real-time positions and activity trajectories on the WEB map. Customized statistical analysis of the data and reports can be generated. The average power consumption of the tracker is less than 50mW, and the average positioning error is less than 20 meters. The system has a large monitoring range and low cost, and has been applied in a wildlife protection station showing good performance.

Key words: narrow band internet of things (NB-IoT), embedded system, positioning and tracking, low power consumption
