A Survey on Enabling Rich Mobile Multimedia Constructed By an Adaptive Mobile Cloud Computing

Mobile Multimedia is a broadcast an rapidly growing segment, and almost every mobile user would have a perceived need for a multimedia-based entertainment application [1]. Mobile cloud computing usually consists of front-end users who possess mobile devices and back-end cloud server. This paradigm allow users to pervasively access a large volume of storage resources with portable devices in a distributed and cooperative way. During the period between uploading and downloading data, the privacy, security and integrity of files need to be guaranteed. The article is concluded with a discussion of several open research problems that call for substantial research efforts. All scheme are lightweight in terms of computational overhead resilient to storage compromise on mobile devices, and do not assume that trust cloud servers are present. We firstly propose an encryption based scheme for the situation of single accessible CS. Next, we propose a coding based scheme for the situation that multiple CSs are available without relying on encryption. Finally we propose a sharing based scheme to further decrease the computation overhead by only relying on exclusive-or operation. Also we extend our work to energy consumptions, providing an analysis of the critical factors affecting the energy consumption, privacy of mobile clients in cloud computing.
