Design of Adaptive Mobile Relay System for Passive IoT Communication Enhancement

Passive Internet of Things (PIoT) devices connected to the network with self-sustaining and low-cost communication. When the PIoT devices in moving, the fluctuations caused by the external environment changing will affect the energy harvesting of PIoT devices, and communication quality will decline eventually. In this paper, we designed an adaptive mobile relay system that relies on interactions between moveable repeaters and PIoT devices to improve the communication quality of PIoT devices during movement.
