LoRaWAN Networks: a More Precise Assessment of the Energy Consumption

In this paper, we evaluate the network energy consumption (NEC) of a LoRaWAN network based on the pure ALOHA protocol. First, we define a reference scenario, which limits the energy consumption to the energy consumed by the radio transceiver. Then, we consider a second scenario in which we add to the energy consumption the energy consumed by the different operation modes of the end-devices after transmission of a packet. Finally, we simulate and compare the energy consumption of both scenarios. Our simulations results show that the energy consumption increases significantly when considering the different operation modes of the end-device.
