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.

Abstract: The present invention relates to a generic packet block applicable to multiple routing schemes in low-power sensor networks and a method of providing the same which reduces operations and information required for a routing scheme in the low-power sensor network and provides flexible extension applicable to various multi-hop routing schemes. The generic packet block includes a generic routing header and routing block, and the method of providing the same is widely applicable to a multi-hop routing. The generic routing header includes a routing packet type, routing address information, and the like, commonly required for the multi-hop routing. The routing block is located in a routing packet body and includes routing cost information changeable depending on a routing scheme, and information changeable depending on a routing operation scheme.

Abstract: Provided is a method and apparatus for managing networks. The method includes defining a set of managed objects of each of the networks to be managed, sending a request for information about the set of managed objects to an agent of the networks to be managed, and recognizing manageable managed objects based on information representing the managed objects, which is transmitted from the agent in response to the request.
