A fault-tolerant energy-efficient computational offloading approach with minimal energy and response time in mobile cloud computing

摘要

The smart-phones are computing devices used to execute resource intensive applications. Despite considerable progress in the past years, smart-phones still have low computing power with some inbuilt problems such as limited battery, resource deficiency, and limited storage. Mobile Cloud Computing (MCC) improves the overall performance of smart-phones by providing extra resources of remote cloud server. Application Offloading is a primary technique used in MCC which increases the capabilities of SMDs. The proposed offloading framework divides the application into tasks, thus, offloading them on remote cloud server for execution. The offloading process in cloud computing extends battery duration and conserves energy. However, it is critical to evaluate the cases where offloading ensure advantages in terms of data transfer, computing power needed, costs of using the clouds, a determined Quality of service (QoS). The paper presents a fault-tolerant energy efficient framework for application offloading with minimal energy consumption and response time.
