According to an exemplary embodiment of the present invention, a method for managing a resource using an apparatus for managing a resource is provided. The apparatus for managing a resource generates a first instance for a first community using a first ontology class about communities including at least one resource as a member according to a goal. The apparatus for managing a resource generates a second instance for a first resource using a second ontology class about resources. Further, the apparatus for managing a resource estimates a relation between the first instance and the second instance.

Method and apparatus for managing resource

Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader

Apparatus and method for transmitting tag

A sensor network management apparatus generates group specification information including requirements corresponding to an externally input service request, and forms a logical sensor network for the service request based on the generated group specification information. USN actuating information relating to USN (ubiquitous sensor network) resources included in the logical sensor network is generated, and USN resources are operated based on the USN actuating information.

Method and apparatus for managing wireless sensor network

A sensor tag includes: a tag chip that receives a supply of a driving voltage that is generated from a radio frequency (RF) signal that is received from a reader and that transmits sensor data to the reader according to a request from the reader; at least one sensor that receives a supply of a necessary driving voltage from the tag chip and that measures corresponding sensor data; and a micro controller unit (MCU) that receives a supply of a necessary driving voltage from the tag chip and that transfers sensor data that is measured from the at least one sensor to the tag chip.

Sensor tag and method of providing service using the same

An IP packet forwarding server forwards an IP data packet between a user terminal and a machine-type communications (MTC) device allocated with a private internet protocol (IP). Such an IP packet forwarding server allocates a call identifier for connection between the user terminal and the MTC device, sets up a packet call to the MTC device and the user terminal using the call identifier, obtains packet forwarding information while setting up the packet call to the MTC device and the user terminal, and forwards an IP data packet between the MTC device and the user terminal using the packet forwarding information.

Method and apparatus for packet call setup

Provided is a method and apparatus for recognizing a radio frequency identification tag reader. In order to obtain protocol addresses of a plurality of radio frequency identification (hereinafter referred to as RFID) tag readers, a request message including a timestamp indicating a generation time is generated and transmitted, and a response message for the request message from one of the plurality of RFID readers is received. When the timestamp included in the response message satisfies a set condition, a hardware address and a protocol address of the RFID reader are extracted from the response message.

Method for recognizing radio frequency identification tag reader and apparatus thereof

Disclosed is a system and method for providing a policy based radio frequency identification service. The system for providing the policy based radio frequency identification service includes a policy vocabulary managing device for generating and managing policy vocabulary based on a policy vocabulary writer's control input, a policy performing resource managing device for generating and managing resource information for performing a radio frequency identification service policy based on a resource designator's control input, a policy rule managing device for generating and managing a policy rule sentence based on a policy user's control input, and a policy rule performing device for performing a radio frequency identification service policy by using a policy rule sentence input based on a policy user's control input.

System and method for providing policy based radio frequency identification service

Provided is an apparatus for detecting a network attack situation. The apparatus includes an alarm receiver receiving a plurality of alarms raised in a network to which the alarm receiver is connected, converting the alarms into predetermined alarm data, and outputting the alarm data; an alarm processor analyzing an attack situation in the network based on attributes of the alarm data and a number of times that the alarm data is generated; a memory storing basic data needed to analyze the state of the network and providing the basic data to the alarm processor; and an interface transmitting the result of the analysis by the alarm processor to an external device, receiving a predetermined critical value from the external device, which is a basis for determining the occurrence of the attack situation, and outputting the critical value to the alarm processor such that the alarm processor can store the critical value in the memory. Equal numbers of hash engines and detection engines for processing the alarms in the network to the number of data groups classified as network attack situations are formed in a line. Therefore, a network attack situation can be detected in real time based on a great number of alarms indicating intrusion detection.
