In recent years, Mobile Cloud Computing (MCC) as a new technology of increasing interest from industry, academia and government has extended infrastructure, platform, and software services offered in a cloud to mobile users. However, the traditional client-server based on mobile service models are not able to meet the increasing demands from mobile users in terms of user experience, services diversity, security, and privacy. In this article, we provide a brief review of MCC, with respect to the basic concept and representative applications (e.g., mobile video streaming and mobile online gaming). The background of new mobile cloud service models is introduced, and then a novel human-centric MCC service model to promote the existing MCC research is proposed.
