Abstract

A method for generating and registering an identification in a wireless sensor network. The method includes generating an identification of a first layer node; transmitting the identification of the first layer node to a second layer node; detecting whether the identification of the first layer node is duplicated, using the second layer node; if the identification of the first layer node is not duplicated, transmitting a determination message from the second layer node to the first layer node; and determining the identification of the first layer node as a determined identification. The method further includes: if the second layer node does not have a determined identification, re-transmitting the identification of the first layer node after a predetermined period of time has lapsed. Therefore, an automatically identification allocating method using a hierarchical structure can be adopted to enable a distributed management.

Claims

1. A method for generating an identification in a wireless sensor network, the method comprising:

generating an identification of a first layer node;

transmitting the identification of the first layer node to a second layer node;

detecting whether the identification of the first layer node is duplicated, using the second layer node;

transmitting a determination message from the second layer node to the first layer node if the identification of the first layer node is not duplicated; and

determining the identification of the first layer node as a determined identification.

2. The method of claim 1, further comprising

re-transmitting the identification of the first layer node after a predetermined period of time has lapsed if the second layer node does not have a determined identification.

3. The method of claim 1, wherein if the identification of the first layer node is duplicated, the second layer node transmits a duplicate message to the first layer node, and the first layer node generates a new identification and transmits the new identification to the second layer node.

4. The method of claim 1, further comprising storing the determined identification of the first layer node in the second layer node.

5. The method of claim 1, wherein the identification comprises a serial number.

6. The method of claim 1, further comprising periodically repeating the generating of the identification of the first layer node, the transmitting of the identification of the first layer node to the second layer node, the detecting whether the identification of the first layer node is duplicated, using the second layer node, if the identification of the first layer node is not duplicated, the transmitting the determination message from the second layer node to the first layer node, and the determining of the identification of the first layer node as the determined identification.

7. The method of claim 1, wherein the determination message comprises the determined identification of the second layer node.

8. The method of claim 1, further comprising:

storing a u-identification of the first layer node comprising the determined identification, a layer information identification indicating a function of the first layer node, a determined identification of the second layer node, and information as to equipment directly connected to the first layer node.

9. The method of claim 7, wherein the u-identification of the first layer node further comprises information as to equipment directly connected to the first layer node.

10. The method of claim 9, wherein the equipment comprises a sensor.

11. A method of registering an identification in a wireless sensor network, the method comprising:

transmitting a notification message from a first layer node to a second layer node;

soliciting for a registration of a u-identification;

registering the u-identification of the first layer node in the second layer node; and

receiving a response message from the second layer node to inform the first layer node that the u-identification has been registered.

12. The method of claim 11, wherein the u-identification comprises at least one of a determined identification of the first layer node, a layer information identification indicating a function of the first layer node, a determined identification of the second layer node, and information as to equipment directly connected to the first layer node.

13. The method of claim 12, wherein when the second layer node registers u-identification, the second layer node writes out a u-identification registering table for the first layer node.

14. The method of claim 12, further comprising storing a u-identification of the second layer node in the first layer node through the response message from the second layer node.

15. The method of claim 13, further comprising soliciting a third layer node for a registration of the u-identification registering table using the second layer node if the u-identification registering table for the first layer node is written out;

and

registering the u-identification registering table using the third layer node.

16. The method of claim 13, further comprising transmitting a table registration response message to the second layer node to inform the second layer node that the third layer node has registered the u-identification registering table.

17. The method of claim 12, further comprising periodically repeating the transmitting of the notification message from the first layer node to the second layer node, the solicitation for the registration of the u-identification comprising the determined identification of the first layer node, the layer information identification indicating the function of the first layer node, the determined identification of the second layer node, and the information as to the equipment directly connected to the first layer node, the registering of the u-identification of the first layer node in the second layer node, and the receiving of the response message from the second layer node to inform the first layer node that the u-identification has been registered.
