Summary:
|
An ambient power-enabled Internet of Things (IoT) device is an IoT device powered by energy harvesting, being either battery-less or equipped with limited energy storage capability [3GPP TR 22.840].
By relying on energy harvested from ambient sources, the ambient power-enabled IoT enables the development of lower-cost, smaller, and maintenance-free devices. This allows IoT deployments to become highly scalable and environmentally sustainable [Y.Ambient-IoT].
However, the unique characteristics of the ambient power-enabled IoT reveal the limitations of conventional data processing and management (DPM) approaches. Specifically, they are challenged by:
1) Severe energy limitations that restrict continuous operation and complex on-device processing;
2) Unpredictable data intermittency caused by frequent power-off and recharge cycles;
3) Strict energy-data dependency, where the timing, volume, and quality of data acquisition are directly dictated by the real-time availability of harvested energy.
Based on the foundational DPM framework [ITU-T Y.4602], this draft Recommendation will specify an enhanced DPM functional architecture tailored for the ambient power-enabled IoT. It extends conventional DPM capabilities to support energy-aware data acquisition and edge-assisted data reconstruction, effectively addressing the challenges of unpredictable energy harvesting status and inherent data quality degradation.
