Abstract

An apparatus for setting a group of a sensor node and a method thereof. According to the apparatus and the method, intensity of a communication signal output from a sensor node is lowered, and the sensor node is set as a group of a master if the communication signal is received in the master, so that the sensor node can be exactly set as belonging to the group of the master.

Claims

1. A method of setting a group of a sensor node, the method comprising:

lowering an intensity of a communication signal output from a sensor node; and

setting the sensor node as belonging to a group of a master upon the lowered intensity communication signal being received in the master.

2. The method as claimed in claim 1, wherein the intensity of the communication signal output from the sensor node is changed to a normal intensity after the sensor node is set as belonging to the group of the master.

3. The method as claimed in claim 2, wherein the intensity of the communication signal output from the sensor node is automatically changed.

4. The method as claimed in claim 2, wherein the intensity of the communication signal output from the sensor node is manually changed.

5. The method as claimed in claim 1, wherein the master allocates a group number to the sensor node after the sensor node is set as belonging to the group of the master.

6. The method as claimed in claim 1, wherein the setting of the sensor node as belonging to the group of the master is automatically performed as the sensor node is powered on.

7. The method as claimed in claim 1, wherein the setting of the sensor node as belonging to the group of the master is manually performed.

8. The method as claimed in claim 1, wherein the communication signal is lowered in intensity enough to prevent reception of the communication signal by masters other then the master.

9. The method as claimed in claim 5, wherein the group number is used to confirm a sensor node when the sensor node transmits sensor data.

10. The method as claimed in claim 7, wherein the manual setting of the sensor node is performed by interfacing with the sensor node.

11. The method as claimed in claim 1, wherein the sensor node detects and transmits to and from the master sensor data including at least one of temperature, illumination, humidity, pressure, and sound.

12. The method as claimed in claim 1, wherein in the sensor node is moved closer to the master to ensure that the lowered intensity communication signal is received in the master.

13. An apparatus for setting a group of a sensor node, the apparatus comprising:

a sensor node outputting a lower intensity communication signal while being set as belonging to a group; and

a master setting the sensor node as belonging to a group thereof upon receiving the lower intensity communication signal from the sensor node.

14. The apparatus as claimed in claim 13, wherein the sensor node changes the intensity of the lower intensity communication signal to a normal intensity after the sensor node is set as belonging to the group of the master.

16. The apparatus as claimed in claim 14, wherein the intensity of the communication signal output from the sensor node is manually changed.

17. The apparatus as claimed in claim 13, wherein the setting of the sensor node as belonging to the group of the master is automatically performed as the sensor node is powered on.

18. The apparatus as claimed in claim 13, wherein the setting of the sensor node as belonging to the group of the master is manually performed.

19. The apparatus as claimed in claim 18, wherein the manual setting of a sensor node to belong to the group of the master is performed through an input unit of the sensor node.

15. The apparatus as claimed in claim_14, wherein the intensity of the communication signal output from the sensor node is automatically changed.

20. A method of setting a sensor node as belonging to a selected master, the method comprising:

decreasing a reception range of a communication signal output from the sensor node to prevent reception of the communication signal by unselected masters; and

setting the sensor node as belonging to the selected master upon the communication signal being received in the selected master.
