GreenLoRaWAN: An energy efficient and resilient LoRaWAN communication protocol

Abstract

Long range wide area network (LoRaWAN) represents a promising low power wide area network (LPWAN) technology in the context of internet-of-things (IoT) that has recently attracted intense research interest. Due to the limited energy resources available on LoRaWAN constituent elements and intermittent power supply of gateways in harsh environments, an energy-efficient communication protocol is constituted of utmost importance in order to prolong network lifetime. Motivated by the aforementioned, this work presents a green, robust, and resilient communication protocol, namely GreenLoRaWAN, which increases energy efficiency, scalability and robustness of the LoRaWAN. The proposed protocol is evaluated by means of Monte Carlo simulations; Performance evaluation results acquired are very promising, revealing an important reduction in energy consumption and increase the duration of network lifetime.
