摘要： Provided is a method of minimizing power consumed by each node in a wireless network when communicating with neighboring nodes.Unlike a conventional synchronous media access control (MAC), the present invention suggests an asynchronous MAC. Thus, the active duration of a node extends only when transmitting a large quantity of data and the extended active duration returns to the minimum active duration again after completing the data transmission.

摘要： A battery-powered RFID tag capable of reducing power consumption and a method of waking up the RFID tag are provided. The battery-powered RFID tag has an activated mode where a general command is detected by decoding a signal received from an RFID tag reader and the general command is executed and a standby mode where the general command is not detected. If a voltage of a continuous wave detected from the signal is equal to or higher than a predetermined voltage or if a wake-up command is detected from the signal, the state of the RFID tag is changed from the standby mode to the activated mode. In addition, the RFID tag is driven by a higher one between the voltage of the continuous wave and a voltage of a built-in battery.
