Computation Offloading Decision in Mobile Cloud Computing: Challenges of Mobile Devices

Abstract

Functionality on mobile devices are ever richer in daily life. Mobile devices have limited resources like battery life, storage and processor, etc. Offloading some computing tasks from mobile devices to the cloud is a way to solve the limitations of battery life and computing capability of mobile devices. Application offloading is energy efficient only under various conditions. This paper proposes an Enhanced Computation Offloading Algorithm, to extend the life time of mobile devices, partition the job as a graph and taking into account the CPU load, state of Charge, wireless network bandwidth, transmission data size. Based on the inputs, the system decide whether to offload the application to the cloud or not. Offloading is an effective method for extending the life time of mobile devices by executing some components of applications remotely.(E.g. processing applications on mobile cloud). Result will demonstrate that the algorithm can significantly reduce energy consumption of mobile device as well as execution time of application.
