Abstract

In order to make the best use of available energy budget, we propose a QoS adjustment method which maximizes the total QoS-provisioning of multimedia tasks with uncertain execution time. This method utilizes the probability distribution of task's execution time to determine an instant QoS level. Our experiments show that the proposed method gives 52% more QoS-provisioning than the conventional method using a constant QoS level derived from the worst-case time.
