Abstract :
Timeout power management policies are widely used in mobile devices for saving power by switching on and off peripherals like display, hard disks, or network interfaces. However the selection of the timeout policy is usually based on heuristic approaches. In this case, a wrong timeout policy may increase the power consumption and degrade the performance. In this work, a probabilistic approach for optimizing both the power savings and performance is adopted to evaluate the feasibility of a timeout power management policy.
