Plan the Access? Generic Hardware Independent Energy Consumption and Efficiency Model for Different LoRaWAN Channel Access Approaches

The growing popularity of LoRa-based solutions, such as weather, environmental, and climate monitoring, has resulted in larger LoRaWAN deployments and increased network load. However, the random channel access method used in LoRaWAN leads to higher message collision probabilities and potential data loss, diminishing the network’s energy efficiency. This article addresses this issue by proposing a hardware-independent model that assesses energy consumption and efficiency in different LoRaWAN channel access approaches. Through simulation and analysis of real energy values, we provide insights and recommendations for optimizing the network performance and energy usage. This study fills a research gap and contributes to the development of more robust and energy-efficient LoRaWAN systems for various application areas.
