- 5. • • • • • Cloud computing isa paradigm in which computing resources such as processing, memory, and storage are not physically present at the user’s location. Mobile cloud computing is a paradigm for mobile applications whereby the data processing and storage are moved from the mobile device to clouds. We introduce three common mobile cloud architectures, computation offloading and capability extending and real-world application. Many applications are too computation intensive to perform on a mobile systems. Offloading such applications to the cloud can save energy and extend battery lifetimes for mobile users.
- 6. • • • The resource-constrained natureof mobile devices, like the limited battery life on mobile devices has been a block to improvements of mobile application. Mobile cloud computing (MCC) is introduced to resolve these conflicts, the cloud serves as a powerful complement to resource-constrained mobile devices. For example, Apple’s iCloud enables users to store and synchronize their data (photos, videos, contacts, etc.) in the cloud.
- 9. • • • • • The architectures definethe way mobile devices are connected to and interact with the cloud The three architectures are Centralized cloud , Cloudlet and Ad Hoc mobile cloud. Centralized Cloud :The cloud resource is placed in a remote centralized cloud infrastructure. Cloudlet :It is a resource-rich server that has Internet access and is connected to mobile devices via LAN. Reduces delay. Ad Hoc Mobile Cloud :This architecture regards a crowd of mobile devices as an “ad hoc mobile cloud,” where the neighboring mobile devices are pooled together for resource sharing.
- 12. • • • • Computation Offloading :Offloadparts of resource-intensive tasks to the cloud. Capability Extending: Cloud computing helps to extend the capabilities of mobile devices in three aspects: computation, storage, and networking. Challenges and opportunities in MCC , with respect to the stochastic characteristics of wireless networks are EnergyEfficient Interactions, Virtual machine migration overhead, Privacy and Security. Some of the real-world applications enabled by MCC are Augmented reality, Remote healthcare and Web applications.
- 14. The modules are: Energy-Saving Module This module utilize the ability of the android application and cloud to run the Content Based Image Retrieval(CBIR) for the image taken. CBIR algorithm takes so much CPU resource if it is executed in smart- phone ,which in turn effects battery life. Offloading CBIR operations to cloud infrastructure proves efficiency of application and power consumption of android system.This can be analyzed using a graph which produce the power consumption of CPU.
- 15. Computation Offloading Module ComputationOffloading is used in android applications where low data transfer rate and huge computation is required. Open source IaaS cloud technology(back-end) called “Open Stack” provides different virtualized instances for hosting the services.
- 16. Security and ReliabilityModule Cloud level security layer is implemented using user-level enceyption for virtual machines network traffic and storage offered by Openstack IaaS cloud technology. The web service level data security is implemented using JSON encoder.

- 23. We described thestate of the art of mobile cloud computing ,from the brewing offloading technology. We unveil the major challenges in mobile cloud computing and potential solutions. Mobile devices geared toward cloud computing will undoubtedly change technology trends as well as our daily lives. Many practical problems remain to be resolved to structure a full fledged mobile cloud system.
