Abstract

Provided is an operating method of a sensor node. The operating method of a sensor node includes receiving a sensing request, adjusting a sensing condition on the basis of the received sensing request, and sensing according to the adjusted sensing condition.

Claims

1. An operating method of a sensor node, comprising:

receiving a sensing request;

adjusting a sensing condition on the basis of the received sensing request; and

performing sensing according to the adjusted sensing condition.

2. The operating method of claim 1, wherein the sensing request is received from another sensor node.

3. The operating method of claim 1, wherein the sensing request is received from a data sink.

4. The operating method of claim 1, wherein the sensing request comprises a sensor node ID corresponding to a specific sensor node.

5. The operating method of claim 1, wherein the sensing request comprises a sensor ID corresponding to a sensor of a specific sensor node.

6. The operating method of claim 1, wherein the sensing request comprises a sensing start time.

7. The operating method of claim 1, wherein the sensing request comprises a sleep time until a sensing is started.

8. The operating method of claim 1, wherein the sensing request comprises a sensing period.

9. An operating method of a data sink in a sensor network, comprising:

obtaining a sensing condition;

creating a sensing request on the basis of the obtained sensing condition;

transmitting the created sensing request; and

receiving a sensing result corresponding to the transmitted sensing request.

10. The operating method of claim 9, wherein the transmitting of the created sensing request comprises transmitting the created sensing request to at least one child node.

11. A sensor network, comprising:

a data sink transmitting a sensing condition; and

at least one sensor node receiving the sensing condition, performing sensing according to the received sensing condition, and transmitting a sensing result to the data sink.
