Abstract
A device and method for adaptively controlling a turn-on time of a transceiver so that power consumption is reduced. The device includes a transceiver for receiving a beacon frame broadcasted by a coordinator which coordinates devices, and a controller for determining whether a period of the beacon frame is changed by checking period information in the received beacon frame. The device further includes a beacon frame arrival-time estimation part for estimating an arrival-time of a next beacon frame to be received, based on the changed period information of the beacon frame, a time-error estimation part for estimating a time-errors of the coordinator and the device based on the changed period information of the beacon frame, and a turn-on time estimation part for estimating a turn-on time of a transceiver based on the estimated beacon frame arrival-time and the estimated time-errors.
