Summary: In this study, an online joint offloading and resource allocation (JORA) framework is proposed to ensure the quality of experience (QoE) of end-users under the long-term mobile edge computing (MEC) energy constraint. Lyapunov optimization is used to solve the long-term QoE maximization problem, and an energy deficit queue is constructed to guide real-time energy consumption. Extensive simulations show the superiority of our proposed methods in performance.
