摘要：Recently, mobile cloud computing has emerged as the state-of-the-art mobile service provisioning. As one of cloud computing service categories, Desktop as a Service (DaaS) enables mobile users to access their virtual desktop in the cloud with any DaaS clients, such as smartphones, tablets. A desktop delivery protocol is responsible for providing the communication channels through the network between the DaaS client and the DaaS platform in order to deliver display updates and other interaction information. There are many challenges in developing a desktop delivery protocol. In order to guarantee the Quality of Experience (QoE) of users, the protocol needs to maintain display quality when processing many different service requirements. On the other hand, due to the limited capacity of the battery of mobile devices, the protocol should be energy-efficient in the procedure of delivering DaaS. To address these challenges, in this paper, we propose a desktop delivery scheme that takes into account both QoE and energy consumption on mobile devices. Our scheme reasonably uses VNC module and MJPEG module of the hybrid remote display protocol (HRDP) to deliver display updates. The experimental results demonstrate that the proposed scheme can provide good display quality of different kinds of service to mobile clients with low energy consumption.
