Mechanisms and challenges on mobility-augmented service provisioning for mobile cloud computing

While mobility is the inherent cause of resource poverty and low connectivity in wireless environment, it also enables the opportunity for surrounding sensing, therefor providing mobility-augmented cloud service becomes the key challenge for the emerging paradigm of Mobile Cloud Computing (MCC). This article provides an overview of the mechanisms and open issues for mobility-augmented service provisioning in MCC. We first outline the concept, system architecture, and taxonomy of research issues. Then we introduce three key mechanisms with respect to mobility augmentation, heterogeneous network convergence and mobile service provisioning. Moreover, we discuss the open challenges to reveal the future direction of MCC.
