ABSTRACT:
A wireless network device includes a transceiver module, a beacon miss module, and a control module. The transceiver module is configured to transition the wireless network device from an inactive mode to an active mode at a wakeup time. The wakeup time is a predetermined time period before a time at which a delivery traffic indication message (DTIM) beacon is expected by the wireless network device. The beacon miss module is configured to count a number of DTIM beacons missed by the transceiver module during each of a first predetermined period and a second predetermined period. The first predetermined period is shorter than the second predetermined period. The control module is configured to selectively adjust the wakeup time during operation of the wireless network device based on the number of the DTIM beacons missed by the transceiver module during each of the first predetermined period and the second predetermined period.
