Since the LoRa modulation is deployed for sensor applications, several papers evaluated this new technology with respect to its energy consumption. Driven by the challenges of energy consumption of wireless sensor applications, many recent works have focused on the power dissipation of communicating sensors.
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 the different node units is first introduced. Then, a full energy model for communicating sensors is proposed.
To estimate and optimize the consumed energy by the sensor node, we propose a full energy model based on LoRa/LoRaWAN technologies. This model is based on LoRaWAN Class A, which is the most energy efficient class in the protocol.
This paper proposes an energy efficient mechanism for LoRa networks, which is based on the user's state and the battery level of the wearable device. Realistic simulations have been conducted to evaluate the system for both one wearable device and multiple wearable devices, using different mobility models.
LoRa is a spread spectrum modulation technique derived from Chirp Spread Spectrum (CSS) technology. It is nowadays a very important technology for applications based on the Internet of Things (IoT), dealing with challenges such as facility monitoring and monitoring of energy consumption in buildings.
It should be noted that some studies conducted on energy consumption in LoRa/LoRaWAN sensor nodes have certain weaknesses. These studies often extract values from datasheets or rely on results obtained from experimental tools [34–36], without presenting an energy model for estimating sensor energy consumption.
