Abstract - Given the advances in mobile telephones, users
start to consider a mobile phone a personal information
processing tool. So users wanted various operations be
performed on the top of mobile devices. Researchers havelong
acknowledged that mobile hardware is necessarily resource-
poor on static client and server hardware. Mobile cloud
computing (MCC) Which combines mobile computing and
cloud computing is a good result for this problem and has
become one of the industry buzz words and a major discussion
topic since 2009.This paper presents a review of the
background, security and open issues in mobile cloud
computing.
Key Words: mobile cloud computing, partitioning,
augmentation.
1. INTRODUCTION
The increasing use of mobile phones is clear from the study
from Juniper Research, which states that the consumer and
enterprise market for cloud-based mobile
applications expected to increase to $9.5 billion by 2014. In
recent years, applications targeted at mobile devices have
started becoming abundant with applications in various
categories such as amusement, social networking, travel,
health, games, business and news. The popularity in the
mobile computing are clear by browsing throughmobileapp
download centers such as Apple's iTunes or Nokia's Ovi
suite. The ground for the mobile cloud computing is that
mobile computing is able to offer a tool to the user whenand
where it is a needed irrespective of user movement, hence
supporting location independence. Indeed, 'mobility' is one
of the important features of a permeating computing
environment where the user is able to continue his/her
work flawless careless of his/her cause. These place the
problem of executing many useful programs that could aid
the user and create a pervasive environment. According to
Tim O'Reilly 'the future of mobility belongs to services that
respond in real-time to information that are supplied either
by nonhuman sensors or by their users. Real time
application demands intensive computing resources to one
character of mobile applications that demand high levels of
reactivity. Location-based social networking process in
mobile applications makesuse of the phone'svarioussensor
data. Nevertheless, extensive use of sensors, such as
obtaining a GPS reading, isexpensive in terms of energy and
this limits the mobile phone in providing the user a better
service through its embedded sensors. Furthermore,
consider applications that call for extensive processing -
image processing for video games, speech synthesis, natural
language processing, augmented reality, wearable
computing-all these demand high computational capacities
thusrestricting the developersin implementingapplications
for mobile telephone sets. problems will be solved in the
future by considering the trends in mobile phone
architecture and battery. This is, in fact, not merely a
temporary technological deficiency, but intrinsictomobility,
and a barrier that needs to overcome to actualized the full
potential of mobile computing. [2].

2. MOBILE CLOUD COMPUTING BACKGROUND
Today, both hardware and software of mobile devices get
more capital improvementsthan before, somesmartphones
such as I Phones, Android serials, window mobile phones
and blackberry, are no longer just traditional mobile phones
with the conversation, SMS, Email and website browser, but
are daily necessities to the user. Still, at any given cost and
level of technology, considerations such as weight, size,
battery life, ergonomics and heat dissipation exact a severe
penalty in computational resourcessuch as processorspeed,
storage size, and disk capacity. Thus, three approaches are
aimed for mobile cloud applications:
1. Extending out the access to cloud services to mobile
devices. In this approach users use mobile devices often
through web browsers, to use software/applications as
services extended by cloud. The mobile cloud is most often
viewed as a Software-as-a-service (SaaS) Cloud and all the
computation and data treatment are usually performed in
the swarm.

2. Enabling mobile devices to act collaboratively as cloud
resource providers. This approach makesuseoftheresource
at personal mobile devices to give a virtual mobile cloud,
which is useful in an ad hoc networking environment
without function of internet cloud.
3. Portable devices using cloud resources are augmented by
the execution of mobile applications. This attack uses the
cloud storage and processing for applications working on
mobile devices. The mobile cloud is thought as an
Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service
(PaaS) cloud. In this partial offloading of computation and
data warehousing is done to clod from the mobile devices
[1].

3. ARCHITECTURE
With mobile cloud computing, mobile network and cloud
computing joined, thereby providing an ideal service for
mobile customers. Cloud computing exists when tasks and
data retained on each device. Applications run on a remote
server and then shipped to the client. Here the mobile
devices connect to the mobile networks through the base
stations; they will set up and manipulatetheconnections(air
interface) And functional interfaces between the mobile
networks and fluid devices. Mobile users send service
requests to the cloud through a WWW browser or desktop
application. The information is transmitted to the central
processors that tied to the serversprovidingmobilenetwork
services. Here, services like AAA (Authentication,
Authorization and Accounting) can store subscriber data in
databases and can offer the users based on Home Agent
(HA). The request of the subscriber is then saved to the
internet. Cloud controllerspresent in the cloud, providesthe
request to the mobile users with the corresponding cloud
services. These services originated based on the concepts of
utility computing, virtualization and service-oriented
architecture. The major use of a cloud computing system is
storing data in the cloud and using technology on the client
to use that data. Various business models rapidly evolved to
harnessthis technology by providing software applications,
programming platforms, data-storage, computing
infrastructure and hardware as services. [3]

4. SECURITY ISSUES
Many sources have presented classifications of security
issues in communication networks. There are five central
goals of security of information system.
 Confidentiality: preventingunauthorizedusersfrom
gaining admission to critical information of any
particular user.
 Integrity: Ensuresunauthorizedchange,destruction
or creation of information cannot take space.
 Availability: Ensuring authorized users getting the
access they need.
 Legitimate: Ensuring that only authorized users
receive access to services.
 Accountability: Ensuring that the users are held
responsible for their security related activities by
arranging the user and his/her body processes
linked if and when necessary. The way these goals
achieved depends on the security policy adoptedby
the service providers.[4]
5. SECURITY COUNTERMEASURES
Secure mobile computing is critical in evolution any
application of wireless networks.

5.1 Security Requirements
Similar to traditional networks, the goalsof securing mobile
computing can delimited by the following attributes:
availability, confidentiality, integrity, authenticity and non-
repudiation.
 Availability: ensures that the intended network
services are available when the intended
parties required.
 Confidentiality: ensuresthat the intended receivers
can use the data and is never revealed to
unauthorized entities.
 Authenticity: allowsa user to find out identityofthe
entity it is communicating with. Without
certification, an adversary can masquerade a
legitimate user, thusgaining unauthorizedaccessto
resources and sensitive information andinterfering
with operation of users.
 Integrity: guarantees that data is never corrupted
during transmission. But the authorized partiescan
change it.
 Non-repudiation: ensures that an entity can prove
the transmission or reception of information from
another entity, i.e., a sender/receiver cannot falsely
deny having received or sent certain data. [4]
6. OPEN ISSUES IN MOBILE CLOUD COMPUTING
There are some issues occurred while implementing the
cloud computing for mobile. These topics can related to
networking, related to limited resources, related to security
of mobile users and clouds. Some subjects explained as
follows:
 LIMITED RESOURCES: having limited resources in
mobile devices makes use of cloud computing in
mobile devices difficult. Basic limitations related to
limited computing power, limitedresources,limited
battery, and low of quality display.
 NETWORK RELATED ISSUES: All processinginMCC
performed along the network. Thus there are some
issues related to the network like bandwidth,
latency, availability and heterogeneity.
 SECURITY: Mobile devices also have to face a
number of troubles related to security and privacy.
To master this problem threat detection services is
now performed at the clouds, but this also has to
face many challenges. There are so many security
threats like, hacking, viruses, Trojan horses in
mobile devices also. The role of global positioning
system (GPS) in mobile devices gives birth to the
privacy issues.
 LOW BANDWIDTH: Bandwidth is one of the big
events at MCC since the radio resource for wireless
networks is much scarce as compared with the
traditional wired networks.
 AVAILABILITY: In MCC service availabilitybecomes
more important issue than that in the cloud
computing with wired networks. Mobile phone
users may not able to link up to the cloud to get
service due to network failures, traffic congestion
and the out-of-signal. [5]
7. CONCLUSION
Mobile Cloud Computing is one of the technology trends in
the fourth coming processas it unitesthe advantagesofboth
cloud computing and mobile computing, and hence
providing optimal services. MCC offers more possibilitiesfor
access services in a convenient way. It is anticipated that
after some more years the number of mobile users will be
using cloud computing on their mobile devices. This report
has provided an overview of mobile cloud computing in
which itsdefinitions, architecture, existingworkapplication,
advantages and challenges have presented. [5]
