Low-Power CoAP for Data Uploads in Next-Generation Power Systems

To address the complex communication scenarios of intelligent terminals in the new power system, the concept of zero-power communication and Internet of Things (IoT) protocols are introduced. In this paper, the original message model of the CoAP protocol is optimized, and the developed message transmission model is proven through experiments to reduce the power consumption of terminal devices during the ACK acknowledgement process, while maintaining a high request success rate under various packet loss conditions. This model shows the potential for use in data reporting applications in modern power systems.
