Tumbler: Energy Efficient Task Scheduling for Dual-Channel Solar-Powered Sensor Nodes
Proceedings of the 56th Annual Design Automation Conference 2019(2019)
摘要
Energy harvesting technology has been popularly adopted in embedded systems. However, unstable energy source results in unsteady operation. In this paper, we devise a long-term energy efficient task scheduling targeting for solar-powered sensor nodes. The proposed method exploits a reinforcement learning with a solar energy prediction method to maximize the energy efficiency, which finally enhances the long-term quality of services (QoS) of the sensor nodes. Experimental results show that the proposed scheduling improves the energy efficiency by 6.0%, on average and achieves the better QoS level by 54.0%, compared with a state-of the-art task scheduling algorithm.
