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. A network manager requests, receives, and obtains information about managed objects of each of sensor networks, especially heterogeneous sensor networks, thereby managing the heterogeneous sensor networks in an integrated way.

Provided is an apparatus and method for preventing air baggage from getting lost using a radio frequency identification (RFID) system. The apparatus for preventing baggage from getting lost, change, or stolen in which a baggage tag storing baggage management information is attached to the baggage and a receipt tag storing the baggage management information is issued to a baggage owner, the apparatus includes: a tag reader reading the receipt tag and the baggage tag in a predetermined area; and a determiner determining whether the tag reader reads the receipt tag including the same baggage management information as the baggage management information of the baggage tag within a predetermined time before and after the tag reader reads the baggage tag. As a result, air baggage is quickly and exactly managed, costs is reduced, and foreign confidence of an airport is increased, thereby preventing baggage from getting lost and exchanged.

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.

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.

An apparatus and method of protecting an RFID password, and an RFID tag access method are provided. The apparatus for protecting an RFID password comprises a recording medium on which the password for the RFID tag is printed, and a disposable shielding member that can be removed physically or chemically, formed on the surface of the recording medium to visually shield the password. Accordingly, the RFID password can be provided securely to a user, and the user can access the RFID tag using the RFID password.

摘要:
A method and an apparatus for providing a service using an RFID tag identifier in an RFID system are provided. The method includes: identifying the RFID tag for providing the service; acquiring an object identifier and a unique item identifier from the RFID tag and determining whether or not each of the identifiers can be interpreted; and disregarding the RFID tag if either of the identifiers cannot be interpreted, and determining whether or not the service should be provided according to validity of the tag identifier of the RFID tag if both of the identifiers can be interpreted. In addition, directly after interpreting the unique item identifier stored in the RFID tag, instead of providing information searches or service, an operation of determining whether or not the tag identifier of the RFID tag is used or issued by an RFID system is performed using the tag identifier stored in the RFID tag. Accordingly, it is possible to prevent the RFID tag issued intentionally or by mistake and having the same object identifier and unique item identifier stored in the RFID tag from receiving erroneous operations or unsuitable service.
