The document discusses mobile cloud computing, including its concepts, architecture, challenges, and applications. Mobile cloud computing extends cloud computing by storing and processing data and applications on remote servers accessible via mobile devices. It allows mobile devices to have their requirements reduced by offloading tasks to the cloud. Key challenges include limitations of mobile devices, communication quality, and dividing application services between mobile and cloud. Solutions involve virtualization, improving bandwidth and delivery times, and elastic application divisions. The document provides examples of mobile commerce, learning, healthcare and gaming applications of mobile cloud computing.

3. INTRODUCTION
• Increased capability of mobile devices
• Accessing internet using mobile devices.
• Growth in emerging mobile devices and in cloud
computing has lead to a new field called mobile
cloud computing.

4. MOBILE COMPUTING
• Mobile Computing is a technology that allows
transmission of data, via a computer, without
having to be connected to a fixed physical link.
• Mobile computing is based on a three concepts:
i. Hardware - mobile devices
ii. software - mobile applications and
iii. Communication-infrastructure of mobile networks,
protocols and data delivery.

5. CLOUD COMPUTING
• cloud computing is storing and accessing data and
programs over the Internet instead in computer's
hard drive.
• The cloud is just a metaphor for the Internet.
• Accessing of data is fast and easy.

6. MOBILE COULD COMPUTING
• The mobile cloud computing is a development
of mobile computing and an extension to cloud
computing.
• The mobile device based computing, data
storage and mass information processing have
been transferred to ’cloud’ .
• Thus the requirements of mobile devices in
computing have been reduced.
• Cloud services are suitable for mobile devices
like smartphone, PDA, Tablet, and iPad.
• Even non-smartphones can achieve mobile cloud
computing.

7. CONCEPT
• Those mobile devices connects with a hotspot or
base station by 3G, WIFI, or GPRS.
• Mobile users send service requests to the cloud
through a web browser or desktop application.
• Then the management component of cloud
allocates resources to the request to establish
connection.
• Major data processing is migrated to ’cloud’ thus
the capability requirement of mobile devices is
limited.

9. CHALLENGES AND SOLUTIONS
• In mobile cloud computing environment, there are
some important factors that affect assessing
from cloud computing. They are:
OVERVIEW OF CHALLENGES AND SOLUTIONS
Challenges Solutions
Limitations of mobile devices Virtualization and Image,
Task migration
Quality of communication Bandwidth upgrading,
Data delivery time reducing
Division of applications services Elastic application division
mechanism

10. LIMITATIONS OF MOBILE DEVICES
• serious limiations:
limited computing capability
energy resources
• Decreased processing capacity, memory, storage.
• Battery technology should be improved in a short
time.
• The increased computing ability and screen
technology - more complicated applications.
• The processing capacity, storage, battery time,
and communication will improve mobile computing.
• Solution: Virtualization and image task migration.

11. QUALITY OF COMMUNICATION
• The data transfer rate in MCC is changing .
• Connection is discontinuous due to network
overlay.
• In wireless network, the network latency delay is
200 ms .
• Mobility of users and weather will lead to changes
in network overlay.
• The handover delay in mobile network is higher
than in wired network.
• Solution: Bandwidth upgrading , Data delivery
time reducing

12. DIVISION OF APPLICATON SERVICES
• Due to limited resources ,some applications cannot
be used as they may consume massive energy.
• The core computing task is processed by cloud ,the
mobile devices are responsible for some simple
tasks only.(divide the application)
• The issues affecting performance of MCC:
—data processing in mobile device,
—network handover delay
—data delivery time.
• To over come it the following are needed:
―optimal division of application
―high-bandwidth
―self-adaptation mechanism
• Solution: Elastic application division mechanisim

13. APPLICATIONS
• Mobile Commerce:
» allows business models for commerce using mobile devices.
» Examples: Mobile financial, mobile advertising, mobile shopping
• Mobile Learning:
» M-learning combines e-learning and mobility.
» Traditional m-learning has limitations on high cost of devices,
low transmission rate, limited educational resources.
• Mobile Healthcare:
» M-healthcare offers hospitals and healthcare organizations a
variety of on-demand services on clouds.
• Mobile Gaming:
» M-game is a high potential market generating revenues for
service providers.
• Other applications:
» Sharing photos/videos
» Keyword-based, voice-based, tag-based searching
» Monitoring a house, smart home systems

14. Conclusion
• Gives the high mobility and scalability.
• Became a research topic in recent years.
• Mobile cloud computing is a highly promising trend
for the future of mobile computing.
• According to a recent study by ABI Research,
more than 240 million business will use cloud
services through mobile devices by 2015
