Abstract:
With the development of communication and computer technology, the conception of Mobile Cloud computing is increasingly expanding. Currently, the Mobile Cloud formed by the nearby mobile devices through ad hoc network has become a new research hot topic. For the services provided by the Mobile Cloud to its internal devices with less bandwidth, lower price, smaller delay and other characteristics, it has attract substantial attention in Mobile Cloud computing. This paper summarizes the related research of the Mobile Cloud , and discusses architecture, mechanism and challenges. First of all, according to the distribution of calculation nodes, communication and control architecture, we divide the architecture into centralized Mobile Cloud and distributed Mobile Cloud , discuss the two types of architecture and its components; secondly, through analyzing the characteristics of Mobile Cloud formation, maintenance and dissolution, its mechanism can be divide into four aspects, that is, incentive mechanism, task allocation and scheduling mechanism, privacy and security mechanism and quality assurance mechanism; finally, based on the summarize of the shortcomings of existing literature on Mobile Cloud research, the four challenges are discussed, the trends of the future development and the further research direction of Mobile Cloud are clarified.
