An adaptive remote display scheme to deliver mobile cloud services

Often referred to as a supercomputer in the palm of the hand, mobile cloud computing is expected to be the next big trend in cloud computing research. Effective remote display protocols are one essential technology for enabling the vision of mobile cloud computing. However, existing remote display protocols have been developed for non-mobile computers such as desktops and are not ready to fully embrace the challenges and requirements distinct to mobile devices in mobile cloud computing settings. Recognizing the importance of energy efficiency on mobile devices, this paper investigates the correlation between energy consumption and various encoding types, and proposes a power-aware encoding scheme to maximize the connection lifespan of battery-driven devices to the cloud. The proposed scheme considers the patterns of power consumption by CPUs and wireless network interface cards for the purpose of reducing power usage for remote display activities. Experimental results show that the proposed hybrid encoding scheme outperforms existing approaches in terms of power efficiency.
