In this paper, we investigate an energy efficiency with performance guaranteed problem in mobile-edge computing.The mobile users desire low energy consumption and performance guaranteed, we propose an energy minimizing optimization problem for mobile-edge cloud computing, that we apply KKT conditions to solve it, and we also present a request offloading scheme for this issue.In particular, the offloading scheme is determined by energy consumption and bandwidth capacity at each time slot.Numerical results demonstrate that our proposed offloading scheme outperforms local computing and entirely offloading method on energy consumption and performance on delay.
