Dear editor,
With the development of wireless communication and computer technology,using mobile devices (MDs) has become more and more popular.However,due to a series of constraints such as heat dissipation,volume and battery capacity,MDs take much time and energy to run some applications and even cannot run heavy applications.As a result,these constraints hinder the further development of MDs.To solve the problem that MDs' performance is restricted by their own limited resources,mobile cloud computing (MCC) has been proposed to augment MDs' capabilities [1].Compared with the client-server architecture which always executes components in the server,MCC needs to make offloading decisions that determine whether components should be of floaded or not according to the optimization objective [2].
