Wireless Sensor Network (WSN) consists of a large amount of low powered nodes which perform tasks like processing, radio transmission-reception, sensing and actuating. To minimize the power consumption in wireless sensor network a dedicated wake-up receiver is used within every sensor node. The wake-up receiver is an additional receiver, which continuously monitors the channel and wakes the rest of the circuit blocks within the node when necessary. In this paper, the authors carried a brief survey on different wake-up receivers.
