    摘要： Provided are an apparatus and method of transmitting and receiving a wake-up signal. The method of receiving a wake-up signal includes the following: operating a radio frequency (RF) receiving unit that receives a wireless signal through an antenna during an SFD detecting time, wherein the SFD detecting time is shorter than a predetermined SFD detecting time period, according to the predetermined SFD detecting time period and detecting a start of frame delimiter (SFD) to indicate that the received wireless signal is a wake-up signal to wake-up a node in a sleep mode; and detecting the wake-up signal by continuously operating the RF receiving unit when the SFD is detected. Power consumption that is used to receive the wake-up signal can be reduced.

    摘要： Provided are an apparatus and method for charging an internal battery in a wireless sensor network. A method for a slave sensor node to charge an internal battery in a sensor network includes estimating an hourly chargeable electric energy rate in a scan phase with a master sensor node, transmitting the estimated hourly chargeable electric energy rate using an association request message requesting association with the master sensor node after recognizing the master sensor node, requesting charging from the master sensor node and performing wireless charging when a power level of an internal battery requires charging, reporting the power level of the internal battery varied by the wireless charging to the master sensor node by predetermined time periods during the wireless charging, and stopping the wireless charging when the power level reported to the master sensor node reaches a predetermined power level.
