Abstract: A wake-up receiver and a wake-up method minimizing power consumption by applying a constant recursive period power off technique are provided to implement high receiving sensitivity and implement a single CMOS single chip without using a special material. A data receiver(430) receives wake-up data. A burst signal receiver(410) receives the burst signal at interval which is set up in the constant recursive period. A duty cycle signal generator generates the signal activating the burst signal receiver for the time interval. If it is activated, a switching unit(420) permits the power in data signal receiving unit, receives wake-up data and disables the duty cycle signal generating unit.

Abstract: A method for recognizing a location based on clustering in a wireless sensor network is provided to minimize a total throughput load and power consumption between the wireless sensor network and a sensor node. Location recognition information between cluster heads is presumed(S201). The cluster heads broadcast a control signal like a beacon signal(S203). A sensor node selects a cluster head managing the sensor node(S205). It is determined whether a location of the sensor node should be recognized or routing should be performed(S207). The cluster head obtains location information of the sensor node(S209).
