摘要：With the increasing variety of mobile applications, reducing the energy utilization of mobile devices is a major challenge in multimedia streaming applications. In this paper we investigate energy-efficient offloading policy for transcoding as a service in a generic mobile cloud system. we explores how to minimize the energy consumption of the backlight when displaying a video stream without adversely impacting the user’s visual experience. we put forward algorithms to solve the fundamental problem and prove the optimality in terms of energy savings. Finally, based on the algorithms, we present a cloud-based energy-saving service. The proposed offloading policy can reduce energy consumption on both mobile devices and the cloud jointly, which provides guidelines for the design of green mobile cloud.
