Abstract
The number of smartphone users and mobile application offerings are growing rapidly. A smartphone is often expected to offer PC-like functionality. In this paper, we present Virtual Smartphone over IP system that allows users to create virtual smartphone images in the mobile cloud and to customize each image to meet different needs. Users can easily and freely tap into the power of the data center by installing the desired mobile applications remotely in one of these images. Because the mobile applications are controlled remotely, they are not constrained by the limit of processing power, memory and battery life of a physical smartphone.

I. INTRODUCTION
The number of smartphone users and mobile application offerings are growing rapidly. Smartphones are often expected to offer PC-like functionality, which requires powerful processors, abundant memory and long-lasting battery life. However, their hardware today is still very limited and application developers are forced to take these limitations into consideration. A number of service providers such Dropbox [1] and Zumodrive [2] provides online storage services to smartphone users in attempt to alleviate the limitations of smartphone storages. However, to the best of our knowledge, there is still no service that offers full computation resources to smartphone users. In this paper, we propose Virtual Smartphone over IP, which provides cloud computing environment specifically tailored for smartphone users. It allows users to create virtual smartphone images in the cloud and to remotely run their mobile applications in these images as they would locally. The motivation is to allow smartphone users to more easily tap into the power of the cloud and to free themselves from the limit of processing power, memory and battery life of a physical smartphone. Using our system, smartphone users can choose to install their mobile applications either locally or in the cloud, as illustrated in Figure 1. Running applications remotely in the cloud has a number of advantages, such as avoiding untrusted applications from accessing local data, boosting computing resources, continuing to run applications on the background and opening up new ways to use smartphones. This paper presents the design and implementation of Virtual Smartphone over IP. Section II describes the basic design of our system and Section III describes a proof-ofconcept prototype that we have implemented. Section IV discuss the possible applications of our system and Section V reports the results of our experiments that demonstrate how we can leverage the performance of mobile applications in the cloud. Section VI discusses the related work in the research community and Section VII concludes this paper.
