Introduction
Mobile cloud computing (MCC) as an emerging computing paradigm integrates cloud computing and mobile computing to enhance the computation performance of mobile devices. The objective of MCC is to extend powerful computing capability of the resource-rich clouds to the resource-constrained mobile devices (., laptop, tablet and smartphone) so as to reduce computation time, conserve local resources, especially battery, and extend storage capacity. To achieve this objective, MCC needs to transfer resource-intensive computations from mobile devices to clouds, referred to as computation offloading. The core of computation offloading is to decide on which computation tasks should be executed on the mobile device or on the cloud, and how to schedule local and cloud resource to implement task offloading. The explosive growth of Internet of Things (IOT) and mobilecommunicationisleadingtothedeploymentoftens of billions of cloud-based mobile sensors and wearable computing devices in near future (Huang & Chae, 2010). Prolonging their battery lives and enhancing their computing capabilities are two key desi
