Summary

Researchers propose two novel, hardware-agnostic dynamic scheduling strategies to manage task execution in batteryless, energy-harvesting IoT systems with unpredictable workloads. These methods, a model-free Reinforcement Learning (RL) agent and an on-the-fly Approximated Prediction (AP) method, treat applications as "black boxes," eliminating the need for prior energy information. The strategies were evaluated against an adaptive task rate approach (AsTAR) and optimized static thresholds using a custom, physically accurate simulation framework incorporating real-world solar data and dynamic LoRa transmission profiles. The analysis exposed distinct operational trade-offs: the AP approach delivers lightweight, near-oracle task throughput; the RL agent provides tunable survival-execution balancing; and AsTAR excels at execution pacing across long energy gaps. The study concludes that while these advanced strategies are critical for severely constrained systems with small capacitors, devices with larger energy buffers can efficiently rely on simpler static policies.

Key takeaway

For Machine Learning Engineers designing batteryless IoT systems, your task scheduler choice must align with the device's energy buffer and operational priorities. For severely constrained systems with small capacitors, evaluate dynamic strategies. Consider the Approximated Prediction (AP) method for near-oracle throughput or the Reinforcement Learning (RL) agent for tunable survival-execution balancing. Devices with larger energy buffers can efficiently utilize simpler, less computationally expensive static policies.
