Towards quality of service for long-range IoT in unlicensed radio spectrum

The flexibility of long-range transmission comes at the cost of stricter legal regulations where duty-cycle approaches limits a transmitter to 1% duty-cycle in the general case. To provide better surveillance service guarantee we propose an activity time sharing mechanism for a pool of devices deployed by a single organization. Devices that need to go beyond the activity time limitation can borrow activity time from other devices. The proposed mechanism has been implemented as a library that can easily be integrated into existing projects.
