A computation offloading scheme for performance enhancement of smart mobile devices for mobile cloud computing

The advancements in the world of mobile technology have enabled computational intensive applications on the latest smart phones. Still Smart Mobile Devices (SMD's) have low potential and are unable to run complex applications due to their limited battery life, storage capacity, processor speed and energy. These limitations of smart phones can be addressed through Mobile Cloud Computing (MCC) which allows the computational intensive applications from smart phones to get offloaded over the cloud environment. In this paper, computation offloading scheme has been proposed that distributes the workload among various Virtual Machines (VM's) on the basis of their distance from the current VM. The offloading will decrease the load on the current VM and increase the performance and speed of execution. The Buffer Allocation Method (BAM) is proposed which will further enhance the performance by eliminating the redundancy of the data to be transmitted during offloading. The results indicate that the speed of execution increases, energy consumption decreases and the load gets balanced due to offloading.
