Abstract

Mobile cloud computing can significantly enhance computation capability of mobile devices by offloading computation from the mobile devices onto the cloud. How to achieve energy-efficient computation offloading remains a challenge issue. For solving this problem, taking reducing energy consumption and shorting application completion time as an objective, this paper proposed an energy-aware computation offloading algorithm. The algorithm formulated computation offloading problem into the energy-efficiency cost minimization problem while satisfying the task dependency requirements and the completion deadline constraint. And this paper presented a dynamic energy-aware computation offloading algorithm. The algorithm consisted of three sub-algorithm of computation offloading selection, clock frequency control and transmission power allocation. Experimental results show that the proposed algorithm can effectively reduce the energy-efficiency cost by optimally adjusting the CPU clock frequency of mobile devices in local computing, and adapting the transmission power in cloud computing while ensure to satisfy the constraints and enhance the scheduling efficiency.
