Abstract

Disclosed is an intermediate node apparatus for configuring a sensor network and a sensor data processing method using the intermediate node apparatus. The intermediate node apparatus may deliver sensor data measured by a sensor node apparatus to a neighboring node apparatus and may store the sensor data in a database.

Claims

1. An intermediate node apparatus for configuring a sensor network, the apparatus comprising:

a data storing unit to receive sensor data from a first sensor node apparatus or a first neighboring node apparatus and to store the sensor data in a database; and

a data delivery unit to deliver the sensor data stored in the database to a second neighboring node apparatus.

2. The apparatus of claim 1, further comprising:

a data searching unit to search the database for sensor data in response to a sensor data request message received from a user terminal; and

a data providing unit to provide the found sensor data to the user terminal.

3. The apparatus of claim 2, wherein the data searching unit delivers, when the sensor data corresponding to the sensor data request message is absent in the database, the sensor data request message to a sensor data collecting server, and receives the sensor data corresponding to the sensor data request message from the sensor data collecting server.

4. The apparatus of claim 2, wherein the user terminal combines the sensor data and map data.

5. The apparatus of claim 1, further comprising:

an apparatus joining unit to search for a second sensor node apparatus regionally associated with the intermediate node apparatus and to allow the intermediate node apparatus to join the second sensor node apparatus.

6. The apparatus of claim 5, wherein the apparatus joining unit allows the intermediate node apparatus to join the second sensor node apparatus through a third neighboring node apparatus authorized to enable joining in the second sensor node apparatus.

7. The apparatus of claim 1, further comprising:

an apparatus joining unit to allow the intermediate node apparatus to join a third sensor node apparatus associated with sensor data requested to be collected at least a predetermined number of times set by the user terminal connected with the intermediate node apparatus.

8. The apparatus of claim 7, wherein the third neighboring node apparatus automatically provides the sensor data to the intermediate node apparatus each time the third neighboring node apparatus measures the sensor data.

9. An intermediate node apparatus for configuring a sensor network, the apparatus comprising:

an apparatus joining unit to allow the intermediate node apparatus to join a neighboring node apparatus connected with at least one sensor; and

a data storing unit to collect sensor data stored in the neighboring node apparatus through a mobile object and to store the collected sensor data in a database.

10. The apparatus of claim 9, further comprising:

a data searching unit to search the database for sensor data in response to a sensor data request message received from a user terminal connected with the intermediate node apparatus; and

a data providing unit to provide the found sensor data to the user terminal.

11. The apparatus of claim 9, wherein the neighboring node apparatus collects the sensor data measured by the sensor connected with the intermediate node apparatus from the intermediate node apparatus, and stores the sensor data.

12. A user terminal connected with an intermediate node apparatus for configuring a sensor network, the user terminal comprising:

a message transmitting unit to transmit a sensor data request message to the intermediate node apparatus;

a data receiving unit to receive the sensor data in response to the request message being received; and

a data combining unit to combine the received sensor data and additional data.

13. The user terminal of claim 12, wherein the data combining unit combines the sensor data and map data and displays the combined data.

14. The user terminal of claim 12, wherein the intermediate node apparatus joins a neighboring node apparatus storing the sensor data corresponding to the request message, and

the data receiving unit receives the sensor data stored in the neighboring node apparatus.

15. The user terminal of claim 12, wherein the intermediate node apparatus collects sensor data by joining a sensor node apparatus associated with sensor data requested to be collected at least a predetermined number of times.

16. The user terminal of claim 12, wherein the intermediate node apparatus collects sensor data by joining a sensor node apparatus regionally associated with the intermediate node apparatus.

17. A sensor data processing method performed in an intermediate node apparatus for configuring a sensor network, the method comprising:

receiving sensor data from a first sensor node apparatus or a first neighboring node apparatus and storing the sensor data in a database; and

delivering the sensor data stored in the database to a second neighboring node apparatus.

18. The method of claim 17, further comprising:

searching the database for sensor data in response to a sensor data request message received from a user terminal; and

providing the found sensor data to the user terminal.

19. A sensor data processing method performed in an intermediate node apparatus for configuring a sensor network, the method comprising:

joining a neighboring node apparatus connected with at least one sensor;

collecting sensor data stored in the neighboring node apparatus through a mobile object; and

storing the collected sensor data in a database.

20. A sensor data processing method performed in a user terminal connected with an intermediate node apparatus for configuring a sensor network, the method comprising:

transmitting a sensor data request message to the intermediate node apparatus;

receiving sensor data in response to the request message; and

combining the received sensor data and additional data.
