In view of the energy optimization problem of mobile cloud computing ,a method of Lyapunov optimization with logarithmic optimization method is proposed .Firstly ,a system model for considering the ordering and pushing energy consumption is established ,and the Lyapunov optimization method is given on the basis of the model .Secondly ,the information is pushed to the user in real time based on the optimized control threshold ,data backlog information and the transmission rate of the channel , which realized the dynamic optimization of the system energy consumption .The computer simulation show s that this method can overcome the interference of channel noise and energy ,and has low energy consumption and data backlog .%针对移动云计算的能耗优化问题,提出了一种对数优化的李雅普诺夫推送方法.该方法首先建立了考虑业务订购、推送能耗的系统模型,并在该模型的基础上给出了李雅普诺夫优化方法;然后,基于优化的控制阈值、数据积压信息以及信道的传输速率实时地向用户推送信息,实现了系统能耗的动态优化.计算机仿真表明,方法能够很好地克服信道噪声能量的干扰,具有较低的能耗和数据积压量.
