Portable wireless systems require long battery lifetime while still delivering high performance. The major contribution of this work is combining new it power management(PM) and it power control (PC) algorithms to trade off performance for power consumption at the system level in portable devices. First we present the formulation for the solution of the PM policy optimization based on renewaltheory. Next we present the formulation for power control (PC) of the wireless link that enables us to obtain further energy savings when thesystem is active. Finally, we discuss the measurements obtained for a set of PM and PC algorithms implemented for the WLAN card on a laptop. The PM policy we developed based on our renewal model consumes three times less power as compared to the default PM policy for the WLAN card with still high performance. Power control saves additional 53% in energy at same bit error rate. With both power control and power management algorithms in place, we observe on average a factor of six in power savings.
