Abstract

A sensor node identification method by a first component of a first layer in a hierarchical sensor network includes: receiving a sensing request including sensor node identification information from a second component of a second layer prior to the first layer; modifying the sensor node identification information by removing an identifier of the first layer from the sensor node identification information when an identifier of the first layer matches an identifier of the first component among the sensor node identification information; and transmitting a sensing request including the modified sensor node identification information to a third component of a third layer subsequent to the first layer.

Claims

1. A sensor node identification method by a first component of a first layer in a hierarchical sensor network, comprising:

receiving a sensing request including sensor node identification information from a second component of a second layer prior to the first layer;

modifying the sensor node identification information by removing an identifier of the first layer from the sensor node identification information when an identifier of the first layer matches an identifier of the first component among the sensor node identification information; and

transmitting a sensing request including the modified sensor node identification information to a third component of a third layer subsequent to the first layer.

2. The sensor node identification method of claim 1, wherein the first component includes at least one of a client, a service provider, and a gateway.

3. The sensor node identification method of claim 2, wherein,

when the first component is the service provider, the second component is the client, and the third component is the gateway,

the sensor node identification information includes information formed by a combination of the service provider identifier, the gateway identifier, and the sensor node identifier.

4. The sensor node identification method of claim 2, wherein,

when the first component is the gateway, the second component is the service provider, and the third component is the sensor node,

the sensor node identification information includes information formed by a combination of the gateway identifier and the sensor node identifier.

5. A component of a hierarchical sensor network for identifying a first sensor node of a first layer in a hierarchical sensor network, comprising:

a receiving unit that receives a sensing request including sensor node identification information from a second component of a second layer prior to the first layer;

an identification information analyzing unit that modifies the sensor node identification information by removing an identifier of the first layer from the sensor node identification information when an identifier of the first layer matches an identifier of the first component among the sensor node identification information; and

a transmitting unit that transmits a sensing request including the modified sensor node identification information to a third component of a third layer subsequent to the first layer.

6. The component of a hierarchical sensor network of claim 5, wherein the first component includes at least one of a client and a gateway.

7. The component of a hierarchical sensor network of claim 6, wherein,

when the first component is the gateway, the second component is the client, and the third component is the sensor node,

the sensor node identification information is formed by a combination of the gateway identifier and the sensor node identifier.
