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 themobile applications are controlled remotely, they are not constrained by the limit of processing power, memory and battery life of a physical smartphone.

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.
• In this paper, we propose Virtual Smartphone over Ipswich 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 intothe 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.
• 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 newways 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-of concept prototype that we have implemented.
• Section IV Discuss the possible applications of our system.
• 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.
BASIC DESIGN
• Our Virtual Smartphone over IP system adopts architecture similar to ones commonly used by server hosting Providers.
• As illustrated in Figure 2, the system is composed of a number of external smartphone clients, a front-end server, a virtual smartphone farm, a management server and a network File system (NFS).
• Virtual smartphone farm is the most important component of our system.
• It is a virtualization environment that hosts a collection of virtual Smartphone images, each of which is dedicated to a Smartphone user.
• In Section III, we discuss in detail about how we have implemented a virtual Smartphone Farm.
• The front-end server admits service requests from Smartphone users across the Internet and establishes Remote sessions to the appropriate virtual smartphone images.
• The frond-end server also allows smartphone users to create, configure and destroy virtual Copyright © 2010 IEEE. Reprinted from IEEE Wow Mom 2010.

Smartphone images. Once a remote session is established, the user can install and run mobile applications on one of these images instead of his own physical smartphone.
The network file system is used by virtual Smartphones for all persistent file storage, in much the Same way that an SD card holds data for physical Smartphones. Since the NFS is easily scalable, it Practically provides each virtual smartphone an Unlimited file storage.
