Abstract

A method for grouping sensor nodes in heterogeneous wireless sensor networks has a sensor network management system. The method includes: receiving a group forming code from the sensor network management system at the respective sensor nodes, wherein the group forming code have sensor conditions and selecting group information from the group forming code in accordance with the conditions at the respective sensor nodes. The method further includes transmitting the selected group information IDs to the sink node.

Claims

1. A method for grouping sensor nodes in heterogeneous wireless sensor networks having a sensor network management system and a sink node comprising:

receiving a group forming code from the sensor network management system at the respective sensor nodes, wherein the group forming code have sensor conditions;

selecting group information from the group forming code in accordance with the conditions at the respective sensor nodes; and

transmitting the selected group information IDs to the sink node.

2. The method of claim 1, further comprising:

sensing signals generated from the sensor nodes neighboring each of the sensor nodes to recognize relationship information on parent, child and sibling sensor nodes thereof; and

transmitting the relationship information to the sink node.

3. The method of claim 1, wherein the group information includes group identifications (IDs) designating groups to which the respective sensor nodes belong.

4. The method of claim 1, wherein when the IDs and the relationship information are changed in accordance with the condition, the changed IDs and relationship information is transmitted to the sink node.

5. A method for transmitting a query code to sensor nodes grouped in heterogeneous wireless sensor networks having a sink node, the sink node is provided with positional shape information indicative of locations at which the respective belong in each group, the method comprising:

searching a target sensor node to which the query code is transmitted based on the shape information when receiving the query code at the sink node; and

transmitting the query code through a path of the positional shape information to the searched target sensor node.

6. The method of claim 5, further comprising:

monitoring the change of the positional shape information.

7. The method of claim 6, wherein the step of monitoring the change of the positional shape information comprises:

checking whether a specific sensor node is released from a current location; and

updating the shape information based on the changed shape information.

8. The method of claim 5, wherein the query code includes a software upgrade for the target sensor node.

9. The method of claim 5, wherein the query code includes a measurement request by the target sensor.
