In the paper Mobile Cloud Computing as Future For Mobile Applications - Implementation Methods and Challenging Issues published by Shahryar S. Qureshi, etc. Authors pointed out that Cloud Computing is expected to bring an innovation in mobile computing, where the mobile devices can use clouds for data processing, storage and other intensive operations. In the paper, authors introduce state-of-the-art Mobile Cloud Computing and its implementation methods.
Nowadays we use desktop computer and servers tied together to create a so called Cloud Computing System.
Mobile Cloud Computing is defined as extension of Cloud Computing with a new ad-hoc infrastructure based on a mobile device.
Simple viewpoint refers that both data storage and data processing is carried outside the mobile devices. Cloud resources are utilized for processing and storage purpose.
1. The advantage of this concept is that Mobile Cloud Computing applications are not constrained to a certain kind of mobile devices or operation systems.
2. No need to worry for the storage capacity and computation speed limitation.
Mobile device view point refers that both data storage and data processing is that nowadays mobile devices (smart phones, tablets etc) are more intelligent and highly developed.
The advantage of such viewpoint is to provide user an ownership (to store and maintain data on personal mobile device).
Mobile Cloud Computing
The Cloud Computing services in a mobile ecosystems incorporating consumer, enterprise, femtocells, transcoding, end-to-end security, home gateway and mobile broadband-enabled services.
Mobile Cloud Computing is made up of a complex network and relationships of and in between Infrastructure Providers, Application / Services Providers (ASP), End users and developers and are connected through Internet.
Mobile Cloud Computing exploits user's information such as location, context, accessed services and network intelligence. Also Mobile Cloud Computing can be a solution to the limitations in Cloud Computing such as limited bandwidth capacity and poor network connectivity.
General purpose Mobile Cloud Computing (GPMCC)
Augmented execution for smart phones using clone clouds
Application specific Mobile Cloud Computing (ASMCC)
Mobile service clouds model enables dynamic instantiation, composition, configuration and reconfiguration of services to be used by the mobile user.
Weblets can be exchanged between mobile devices and clouds. Using elastic computing resources provides solution for authentication, secure session management, secure migration between weblets running mobile devices and those on clouds.
RESTful web services are to offload computational capacity, storage and security (of mobile device) to cloud by utilizing the RESTful web services.
Some Potential Barriers and Issues
Barriers
1. Only SaaS has been implemented in Mobile Cloud Computing because of mobile devices ' insufficient storage capacity, battery, poor display and computing power. (Opportunities for PaaS and IaaS)
2. Absence of standards.
Limited scalability, unreliable availability of service and service provider lock-in.
Potential Issues
1. Resource poverty of mobile devices
2. Network bandwidth and latency
3. Network availability and intermittency
4. Security concerns
Future Search
1. Security issues
2. The mobile cloud architecture for heterogeneous wireless network should be investigated
3. A single access platform is required to establish for MCC on the various operating systems platform (e.g. Android, Symbian, Apple iOS, Chrome, MeeGo, Windows Phone)
