Abstract
For edge devices, pushing the task to other near devices has become a widely concerned service provision paradigm. However, the energy-constrained nature of edge devices makes optimizing for Quality of Service (QoS) difficult. We choose three factors as QoS: the delay limitation, the CPU usage of terminal and energy consumption. Due to the delay limitation of different tasks for edge computing and the different rates in heterogeneous wireless networks, we propose a network selection task migration algorithm based on Q-learning that captures the trade-off between QoS and energy consumption. Our approach can automatically choose a suitable network to perform task migration reasons about the task’s QoS requirements and computing rate in 4G network, Wi-Fi, Device-to-device (D2D). We demonstrate a working prototype using the YOLOv3 on the Vivo X9 devices. Based on real hardware and software measurements, we achieve 27.79% energy saving and 35% reduction in delay.
