Reward-Based Voltage Scheduling for Hard Real-Time Systems with Energy Constraints?

Reward-based scheduling has been investigated for flexible applications in which an approximate but timely result is acceptable. Meanwhile, significant research efforts have been made on v ltage schedulingwhich exploits the tradeoff between the processor speed and the energy consumption. In this paper, we address the combined scheduling problem of maximizing the total reward of hard real-time systems with a given energy budget for the general task model. We present anoptimal off-linealgorithm and an efficient on-line algorithm for jobs with their own release-times/deadlines. Our work is the first significant result for the general task model.
