Energy-Efficiency Approach for Long Range Wireless Communication

Abstract

According to recent researches, the wireless sensor networks (WSN) which consume low levels of energy become more and more popular nowadays, so the research trend of optimizing energy for WSNs is rapidly increasing. LoRa technology is a modulation technique that provides long-range transfer of information and low power consumes. Besides, LoRaWAN is a network protocol that optimized for battery-powered end devices. The LoRa and LoRaWAN can be considered a suitable candidate for WSNs, which can reduce power consumption and extend the communication range. In this paper, we studied adaptive mechanisms in the transmission parameters of the LoRa network and proposed an energy-optimized solution for the adaptive algorithm. This research not only introduced the reference hardware of a sensor node in WSNs but also conducted experiments on typical LoRa network infrastructure
