4. • Mobile Cloud Computing (MCC) is a combination of three main
parts; they are mobile device, cloud computing and mobile internet.
• MCC integrates the cloud computing into the mobile environment
and overcomes obstacles related to the performance (e.g., battery
life, storage, and bandwidth), environment (e.g., heterogeneity,
scalability, and availability), and security (e.g., reliability and
privacy) .
Abstract

5. Mobile Computing
• It is a technology that allows transmission of data, audio and video
through a smart phone or any other wireless enabled device without
having to be connected to a fixed physical channel
• The mobile computing means to access data through portable devices
like PDA, smart phone, tablet and so on..

6. Cloud Computing
 Cloud computing is collection of remote servers in network to allow
centralized data storage and online communication to computer services
or resources .
 Internet and not on personal devices to provide on-demand access.
Applications are run on a remote server, all the processing task done on
remote server and then result sent to the user.

7. Mobile Cloud Computing
 Mobile Cloud Computing refers to an infrastructure where both the data
storage andthe data processingoccuroutside of the mobile device.
 Mobile cloud applications move the data storage away from mobile
phones into the cloud ,bringing applications and mobile computing not
only to smart phone users but also to a much broader range of mobile
subscribers.

8. Problem Domain
The data of owner is stored on the cloud server;
once the data is stored the owner does not have
that data on his own device. Thus, there is risk
related to data security and confidentiality of the
data.So, data confidentiality is also a concern of
data owner.

9. Solution Domain
In this system design three main entities are involved:
Mobile User (MU): Mobile user/client is a person who
utilizes the storage services provided by Cloud service
provider (CSP).Cloud Service Provider (CSP): CSP
provides storage services to client. CSP is also
responsible for operating, managing and allocating cloud
resources efficiently. Trusted Third Party (TTP): TTP
installs co processors on remote cloud; who is associated
with a number of registered mobile user/client. Co
processor provides secret key (SEK) to mobile user and
is also responsible for generating message authentication
code for mobile client.

10. The primary constraints for mobile cloud
computing are limited energy and wireless
bandwidth. So the motivation behind this paper is
to test weather cloud applications good solution to
improving battery lifetime of mobile device.
Motivation

11. Objective and Scope
Mobile Phone application are exploding in popularity
and demanding more computing resources to perform
compute intensive tasks. Despite the rapid
development of heterogeneous set of mobiles devices,
they are intrinsically limited by storage, processing
power and battery lifetime.Hence,there is an
increasing need for abundant resources offered by
cloud for the benefit of mobile phones, thus rendering
a new research area called the mobile cloud
computing

12. Methodology / Research plan
Our vision and research agenda of a Cloud architecture is the
seamless integration of cloud let and public cloud, and
infrastructure specialization for mobile applications. We believe
the dominant architecture will be the regional data centers of
public cloud providers. Cloud let is necessary to reduce the delay
of latency sensitive perception applications. There are two
convincing deployment settings. One is for wireless providers to
deploy cloudlet like nodes within their wireless access networks as
a premium service for its subscribers. The other is for cloud
providers to co-locate cloud resources in wireless access networks
through co-location agreement with wireless providers. For
optimal performance, we believe the middle tier needs to be
integrated with the region data centers of public cloud seamlessly.

13. Expected Outcome
In this paper, we envision that these fundamental new
capabilities will enable mobile users to seamlessly
utilize the cloud to obtain the resource benefits without
incurring delays and jitters and without worrying about
energy. By thus empowering mobile users, mobile
computing will be able to break free of the fundamental
constraints that have been keeping us from transform
many areas of human activity. We envision the future of
mobile computing applications will be built on top of a
rich Eco-system of basic mobile cloud services.

14. Conclusion
Paper has provided an overview of mobile cloud
computing in which its definitions, security, issues
and advantages have been presented. Mainly it
discussed about security of data stored in cloud and
importance of data security. This paper has explored
a number of mechanisms for providing data security
so that Mobile Cloud Computing can be widely
accepted by a number of users in future. It also
proposed a mechanism to provide confidentiality,
access control as well as integrity to mobile users.
