%X Most nodes in a wireless local area networks (WLAN) arc powered by battery due to mobility requirement. Power conservation is significant for the nodes to prolong their run-time. Power management (PM) is presented in the IEEE 802. 11 standard, which allows nodes to enter dozing mode to save power when they are not engaged in data deli- very. I}he PM was modeled and analyzed so that the packet delay, the number of successive dozes, the active time, and the number of switches between active and doze modes were all derived. A delay aware power management (DAPM) scheme, which is suitable for IEEE 802. 11 infrastructure WI_ANs, was proposed and analyzed. hhe DAPM was able to help nodes seek the optimal dozing period so that the power consumption is minimized while the given delay requirement is met.
