Energy Efficient 5G LoRa Ad-Hoc Network for Smart Grid Communication

With the advent of Energy Internet and the goal to enable the smart grids (SG), there have been advancements in both 5G and Internet of Things (IoT) technologies to achieve this. The circumstances of distribution power networks are getting more and more complicated with the wide coverage of modern power system, and there are diversified communication blind areas. In this paper, a communication framework based on 5G LoRa Ad-Hoc network is presented to support the diversified grid circumstances. Based on this framework, multiple LoRa can establish communication links with the SG cloud server though 5G LoRa gateway. Moreover, the flexibility in 5G LoRa Ad-Hoc networking configurations allows higher management in resource allocation and topology algorithm, which realizes better resource utilization, and improves network scalability and energy efficiency. Real measurement and simulation results show that proposed strategy is scalable and robust, and also offer supplementary and energy-efficient room for improvement with respect to existing approaches.
