摘要： A sensor actuator node includes a sensor unit for generating sensing information on circumstantial changes; a communications unit; a countermeasure information generation unit for generating countermeasure information to the circumstantial changes; and a drive unit for driving one or more actuators. When the sensor actuator node acts as a host node, the sensing information becomes main sensing information, the countermeasure information generation unit generates the countermeasure information based on the main sensing information and selectively transmits the countermeasure information to the adjacent sensor actuator nodes via the communications unit, and the drive unit drives the actuator based on the countermeasure information. When the sensor actuator node acts as a non-host node, the sensing information becomes auxiliary sensing information, and the drive unit drives the actuator based on the countermeasure information selectively transmitted thereto by the host node.
