摘要:
An apparatus for managing a plurality of wireless sensor networks selects a configuring policy according to a characteristic of each wireless sensor network and configures a network with the selected configuring policy for management. When an error occurs in the wireless sensor network, the apparatus performs error diagnosis based on a configuring policy applied to the error-detected wireless sensor network, infers a cause of the error, and provides an error recovery method corresponding to the inferred cause of the error to the error-detected wireless sensor network.

The present invention relates to a device and method for managing a memory of an RFID tag. The present invention provides an apparatus for managing a user memory of an RFID tag. The apparatus includes a memory usage information storing unit, a memory registration-management unit, and a memory referring unit. The memory usage information storing unit stores memory usage information. The memory registration-management unit searches information regarding an empty region of the user memory by the memory usage information storing unit, provides the searched information to the specific application system, receives memory usage information regarding the specific data that is to be stored in the user memory from the specific application system, and stores and manages the memory usage information regarding the specific data in the memory usage information storing unit, if the specific application system requests the user memory to store specific data. The memory referring unit provides memory usage information regarding the specific data, which is stored in the memory usage information storing unit, to the application system that requests to refer to the specific data if referring to the specific data is requested. According to the present invention, it is possible to systematically and efficiently manage data that is stored in the user memory region of the RFID tag by a plurality of users, and to prevent the storage positions of a plurality of data that are stored in the user memory region of the RFID tag from overlapping. As a result, it is possible to prevent a loss of data to be stored in the user memory region of the RFID tag.

The present invention relates to a method of searching a metadata server that searches ubiquitous sensor network (USN) metadata servers in a distributed environment. The present invention stores location information on the metadata servers by using a location-server cluster and searches a location of a metadata server in which a specified resource metadata is stored, during a metadata searching request by a client. Accordingly, the present invention can provide a simple and consistent interface to the client using the metadata management servers in terms of the metadata servers and can improve the clarity of service development and can reduce the entire development costs and the maintenance and repair costs.

An event surveillance system includes: a network camera for monitoring real-time video images to perform event tracking on an event occurred therein; and at least one machine-to-machine agent, connected to the network camera and devices in a network, for providing protocols for data communications between the network camera and the devices. If the machine-to-machine agent receives information on the event occurred in the network camera, the machine-to-machine agent requests the devices to provide event information for use in verifying accuracy of the event and verifies the accuracy of the event based on the event information provided by the devices. The network camera monitors in real time the event verified to be accurate.

Provided is a pop-noise removing method. The pop-noise removing method analyzes an acoustic noise, occurring when receiving digital broadcasting under a weak electric field environment, and reduces a pop-noise on the basis of the analyzed result, for transferring digital broadcasting with a minimized pop-noise to consumers. Accordingly, an output of the pop-noise of digital broadcasting can be minimized
