Energy efficiency is the key requirement to maximize sensor node lifetime. Sensor nodesare typically powered by a battery source that has finite lifetime. Most Internet of Thing (IoT)applications require sensor nodes to operate reliably for an extended period of time. To design anautonomous sensor node, it is important to model its energy consumption for different tasks. Eachtask consumes a power consumption amount for a period of time. To optimize the consumed energyof the sensor node and have long communication range, Low Power Wide Area Network technologyis considered. This paper describes an energy consumption model based on LoRa and LoRaWAN,which allows estimating the consumed power of each sensor node element. The definition of thedifferent node units is first introduced. Then, a full energy model for communicating sensors isproposed. This model can be used to compare different LoRaWAN modes to find the best sensornode design to achieve its energy autonomy.
