A real-time feedback scheduler for environmental energy with discrete voltage/frequency modes
We address the problem of real-time scheduling inherent to energy harvesting real-time systems. We propose a feedback scheduler for energy harvesting systems (FS-EH) in a soft real-time context on a DVFS processor. This solution computes the CPU speed with taking into account the energy levels and the executions time variability. The proposed approach shows experimentally a good compromise between the available energy and the processor workload.
