- Abstract
- Provided are an adaptive communication method and a sensor node for performing the same. The sensor node adaptively selects transmitted signal output strength and a wakeup zone of transmitted data based on a received signal strength indication of a control packet received from a sink node and existence of an obstacle acquired through a sensor, and transmits data based on the adaptive selection. Also, during an operation as a receive mode, the sensor node wakes up and determines whether to receive the data from the transmit node based on wakeup zone configuration information per sensor node received from the sink node and a wakeup zone selected by a sensor node currently operable as a transmit node.
