A green analysis of mobile cloud computing applications

Abstract

With the widespread of rich mobile applications, the usage of mobile devices, especially smart phones and tablets, has become popular nowadays. However, battery in the mobile devices often limits continuous usages with its small size and capacity. Therefore, power consumption of mobile devices is a critical issue, not only for extending lifetime use of mobile devices, but also for creating a green IT which is a raising concern in academic and industrial communities. The goal of this paper is to investigate the power consumption of mobile devices and resource usages for various applications. To meet the goal, we have performed a number of experiments and detailed evaluations of resource usages and power consumption for various applications using a number of tools. In addition, we have measured performance metrics for applications either using a mobile device or running in the Amazon cloud. We examine the impact of various factors and provide insights on power consumption for different mobile applications.
