Energy consumption modeling for communicating sensors using LoRa technology

Sensor nodes are typically powered by a chemical battery source that has a finite lifetime. To design an energy efficient self powered node, it is important to model the energy consumption of the wireless sensor. This paper describes an energy consumption model which is used to analyze node autonomy. This model allows to estimate the power consumption of each element of the sensor node. The definition of the different node units is first introduced. Then, a complete energy model for sensor node is derived using LoRa (Long Range Communication) technology.
