LoRaWAN is a wide area network solution for large-area sensor networks; long range (LoRa) transmissions can be achieved, with low power transmissions, but only for very low bandwidth. One of the main challenges is the lack of guarantees in LoRaWAN, which may cause a sensor not to be heard for days. In this paper, we create a real-time schedule for LoRaWANs, compatible with the LoRaWAN standards, and achieve close-to-zero collisions in packet reception at the application. Through NS-3 simulations, we show the reliability and scalability of our solution.
