Mobile Computing Rapid progress of mobile computing have become a powerfultrend in the development of many fields, including IT,commerce, industry, etc. Mobile devices have limited resources (e.g., battery life,storage, and bandwidth) and communications (e.g., mobilityand security). The limited resources significantly handicap the quality ofservices offered by mobile computing.
Mobile Cloud Computing Cloud Computing has been identified as the next generation’scomputing infrastructure. Cloud Computing allows access to infrastructure, platforms,and software provided by cloud providers at low cost, in anon-demand fashion. Mobile Cloud Computing is introduced as an integration ofcloud computing into the mobile environment, to bring newtypes of services and facilities for mobile users.
Mobile Cloud Computing Definition“Mobile Cloud Computing at its simplest refers to aninfrastructure where both the data storage and the dataprocessing happen outside of the mobile device. Mobilecloud applications move the computing power and datastorage away from mobile phones and in to the cloud,bringing applications and mobile computing to not justsmart phone users but a much broader range of mobilesubscribers”.- Mobile Cloud Computing Forum (MCC-forum, 2011)
How it Works? Data processing and storage are moved from the mobiledevice to powerful and centralized computing platformslocated in clouds. They are accessed by mobile devices over a wirelessconnection using an app or a web ationServiceProvider

Google’s Voice Search When you talk to Android's voice recognition software, thespectrogram of what you've said is chopped up and uploadedto Google's cloud servers. It's then processed, using the neural network models. There are a couple of layers in processing speech. First Googletries to understand the consonants and the vowels. That is thefoundational layer. Next, it uses those to make intelligentguesses about the words. And then higher.
Advantages for Mobile Users?Extended battery lifetime of mobile devices Using computation offloading techniques, large computations andcomplex processing is migrated from resource-limited mobile devices toresourceful cloud servers. This avoids taking a long application execution time on mobile devices,resulting in a significant reduction in power consumption. Large-scale numerical computations and shows that up to 45% of energyconsumption can be reduced for large matrix calculations. Offloading a compiler optimization for image processing can reduce upto 41% for energy consumption of a mobile device. Migrating mobile game components to cloud servers can save 27% ofenergy consumption for computer games and 45% for chess games.
Advantages for Mobile Users?Improving data storage capacity Storage capacity is also a constraint for mobile devices. Mobile cloud computing is developed to enable mobile users tostore/access large amounts of data on the cloud through wirelessnetworks. For instance, Google Photos allows users to upload unlimited photosand video to the clouds, even immediately after capturing. Users mayaccess their images and videos from any connected device. Users can save considerable amount of energy and storage space ontheir mobile devices since all images are sent and processed on theclouds.
Advantages for Mobile Users?Improved processing power Mobile cloud computing helps reducing the running cost for intensiveapplications that take long time and large amount of energy whenperformed on the limited-resource mobile devices. Cloud computing can efficiently support various tasks for datawarehousing, managing and synchronizing multiple documents online. For instance, clouds can be used for transcoding, playing chess, orbroadcasting multimedia services. In these cases, all the complex calculations for transcoding or offering anoptimal chess move that take a long time when perform on mobiledevices will be processed quickly on the cloud.
Advantages for Mobile Users?Improved reliability Data and application are stored and backed up on a number of cloudservers. This reduces the chance of data and application lost on the mobiledevices. Cloud can remotely provide security services such as virus scanning,malicious code detection, authentication, etc.
Advantages for ServiceProviders?Dynamic provisioning Dynamic on-demand provisioning of resources.Scalability Easily add and expand services without or with little constraint on theresource usage.Multi-tenancy Share resources and costs to support a variety of applications and largenumber of users.Ease of Integration Multiple services from different service providers can be integratedeasily.

The high-technology community has argued for many years about the precise definitions of centralized computing, parallel computing, distributed computing, and cloud computing. In general, distributed computing is the opposite of centralized computing.
