Dynamic Power Management for Embedded Wireless Devices

Abstract:

The energy consumption of WLAN card makes up a significant proportion in the embedded system, which makes the effective power management on WLAN card play an important role on energy-saving and WLAN card longevity. This paper introduces a method of dynamic power management for WLAN card: manipulating the WLAN card driver to achieve the transition state of the WLAN card, acquiring WLAN card load which ultimately achieves the dynamic power management optimization algorithm. The experiment is presented to prove the feasibility of the implementation for the purpose of energy consumption saving on WLAN card.
