Abstract:
Embodiments of the present invention relate to connecting different types of data. According to an embodiment of the present invention, a method for connecting NoSQL data and linked data comprises the steps of: converting NoSQL data into resource description framework (RDF) data, and issuing the converted RDF data as linked data; collecting extended linked data extended by connecting the issued linked data and external linked data; and storing the collected extended linked data as the NoSQL data. According to embodiments of the present invention, a dynamic virtuous circulation structure capable of utilizing the advantages of each of the NoSQL data and the linked data and mutually compensating for the disadvantages thereof can be constructed.
Abstract:
Provided are an apparatus and a method for detecting an event and automatically generating metadata. The apparatus and the method generate metadata of an event based on sensor information which is acquired by a sensor and generate metadata of an object based on object information which is acquired by an RFID tag. The apparatus and the method generate one event metadata by connecting the metadata of the event with the metadata of the object.

Abstract:
The present invention provides to an object tracking method through automatic recognition of a sensor node according to movements of an object about the occurrence of an event based on a large sensor network. A moving route of the object required to be tracked is displayed on a GIS map based on a global identifier of the object periodically provided by each sensor node so that continuous tracking is possible. A system is also built in low costs as the tracking with few personnel is possible.

Abstract:
PURPOSE: A sensor network driving method and a device thereof are provided to effectively form and operate a sensor network. CONSTITUTION: A sensor network generating unit(12) generates a logical sensor network comprising a physical USN(Ubiquitous Sensor Network) based on group item information. The sensor network generating unit generates USN driving information for physical USN resources based on metadata stored in a resource metadata storage unit. A sensor network control unit(13) individually drives the USN resources comprising the logical sensor network based on the USN driving information. The sensor network control unit receives driving results from the USN resources.

Abstract:
PURPOSE: A hierarchical sensor network structure and a resource identifier issue method thereof are provided to hierarchically grant a resource identification system to individually access and control resources of a sensor network. CONSTITUTION: A gateway(20) receives a sensing request. The gateway transmits the received sensing request to a sensor node. The gateway receives and collects sensing information from the sensor node to provide the same. Each of clients(10-10_n) transmits the sensing request to a lower layer of the gateway through the gateway. Each of clients receives the sensing information.

Abstract:
PURPOSE: An unmanned monitoring device for tracing an event and an event tracing method are provided to reduce the misinformation ratio of an event by using an unmanned monitoring device. CONSTITUTION: A user interface unit(210) receives condition information about an event generated in a sensor field. The user interface unit receives a response method about the event from a user. A control engine(220) receives the condition information from sensor nodes. The control engine selects specific sensor nodes which receive the condition information. A cooperation engine(250) transfers the condition information to the control engine. The cooperation engine transfers the condition information to the selected specific sensor node.

Abstract:
PURPOSE: An RFID code searching apparatus by using a keyword is provided to accurately supply detailed information of a product by filtering a code of a product. CONSTITUTION: Database(83) stores a keyword and a code. A search processing unit requests a code search about a keyword which is inputted from an external input interface unit and the searched code to the external input interface. A code searching unit(85) searches for the code about the keyword in the database. The search processing unit converts the searched code based on a filtering condition and includes a respond processing unit(842).
Abstract:
PURPOSE: A virtual sensor network configuration system is provided to easily obtain the information in which a user or an application service is needed. CONSTITUTION: A physical sensor network constitution management(300) approaches to a sensor node through one or more sensor node objects. The physical sensor network constitution management part obtains the sensing value. The physical sensor network constitution management part maintains the information of one or more sensor node objects. A virtual sensor network constitution management part search the information of one or more sensor node objects existing in the physical sensor network constitution management part. The virtual sensor network constitution management part constitutes the virtual sensor network by selecting one or more sensor nodes.
Abstract:
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.
