STOC: Energy Cost Models of Smartphones for Task Offloading to the Cloud

Improving computing ability of smartphones and also prolonging their battery life can be achieved by offloading the task to the cloud. However, task offloading introduces a communication cost for those devices. Therefore, consideration of the communication cost is crucial for the effectiveness of task offloading. To make task offloading beneficial, one of the challenges is to estimate the energy consumed in communication activities of task offloading. Accurate energy estimation models will enable these devices to make the right decisions as to whether or not to perform task offloading, based on the energy cost of the communication activities. If the offloading process consumes less energy than processing the task on the device itself, then the task is offloaded to the cloud Here energy models during task offloading can be constructed during both uploading and downloading process using 3G/4G and Wifi. Also an analysis report is prepared giving detailed information of the energy consumed during uploading and downloading video files. Storage as a service (SaaS) aspect of the cloud is utilized for task offloading.
