SENSOR ACTUATOR NODE AND METHOD FOR HANDLING CIRCUMSTANTIAL CHANGES IN SENSOR ACTUATOR NETWORK USING SAME
First Claim
1. A sensor actuator node in a sensor actuator network, wherein the sensor actuator node operates at least one device by driving an actuator of each device and acts as at least one of a host node and a non-host node at a time, the sensor actuator node comprising:
- a sensor unit for sensing circumstantial changes and generating sensing information on the circumstantial changes;
a communications unit for communicating with adjacent sensor actuator nodes;
a countermeasure information generation unit for generating countermeasure information to the circumstantial changes; and
a drive unit for driving the actuator,wherein when the sensor actuator node acts as the host node, the sensing information generated by the sensor unit 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; and
wherein when the sensor actuator node acts as the non-host node, the sensing information generated by the sensor unit becomes auxiliary sensing information, and the drive unit drives the actuator based on the countermeasure information selectively transmitted thereto by the host node.

Abstract
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.
