Abstract:
An RFID apparatus for adjusting the recognition distance and an RFID information operating method using the same are provided to control the recognition distance of an RFID tag by adjusting the length of an antenna. An RFID(Radio Frequency ID) chip(100) stores RFID information. An antenna(200) extracts the RFID information from the RFID chip and then transmits it to an RFID reader. A switch(300) controls the length of an antenna so as to set up transmission of the RFID information. If the antenna length is set shortly up, the RFID reader cannot receive the RFID information.
Abstract:
A reactive routing method in a low power sensor network and a system thereof are provided to support the mesh topology in the low power sensor network consisting of sensor nodes which have a narrow operational range, low data transfer rate and cheap property. A route determination controller(110) determines whether a path from a transmission node to a destination node exists in a routing table. If the path does not exist in the routing table, a transmission node controller(120) transmits a route request message to a multicast address. A destination node controller(130) controls the destination node, obtains information about a path to the transmission node, and then transmits a route response message to the transmission node.
Abstract:
A multiple routing applicable generic packet block in a low power sensor network and a providing method thereof are provided to minimize a process and information required for the routing method in the low power sensor network by designing the packet information with the generic packet block and applying the packet information to the routing. A multi hop routing module(140) is positioned between a logical link interface(120) and a network layer(130) to closely use the information of a PHY/MAC layer. A routing packet semantics(143) includes the information about the start of the routing packet and the type of the routing. A generic routing header(146) is comprised to include the type of the routing message. The generic routing header includes one of an address used to the routing, the maximum hoping number delivered to the routing, the transmitted hopping number, and a destination node address of the routing. A routing block(145) includes the information about the routing type and the routing message type. The generic packet block includes a routing body defining the routing block.
Abstract:
A method and an apparatus of code resolution by using an application data area in an RFID system are provided to enable a terminal to obtain a code analysis method by approaching a target object without any restriction of a hierarchical structure of an object. An information readout terminal senses a tag storing the information for analyzing an object ID(S410), and analyzes the code information including the object ID of the sensed tag. When the analysis of the code information is disabled(S420), the information readout terminal obtains the information stored at a user data region of the tag which is the position information of an object ID analyzing server(S430). The information readout terminal uses the obtained position information to obtain the code information related to the object ID based on the request of the code information.
Abstract:
An apparatus for providing sensor network services and a method therefor are provided to connect with a corresponding sensor network server and receive the sensor network services by using the location information of the sensor network services included in a response message, thereby enabling a mobile communication terminal to receive various types of sensor network services without a separate sensor network module. A media reading unit(210) reads information stored in information storage media. A location information request unit(220) generates a query message including the information and transmits the query message to a code information provision device(250) so as to request the location information of a sensor network service. A location information reception unit(230) receives a response message including the location information of the sensor network service corresponding to the information from the code information provision device. A service request unit(240) connects with a corresponding sensor network server(260) on the basis of the location information of the sensor network service included in the response message to request the sensor network service.
Abstract:
An RFID(Radio Frequency IDentification) system equipped with an automatic application program recognition function and a method thereof are provided to enable an RFID reader to recognize an application program needed for a service without any user decision or selection by using information stored in an RFID tag or a response message of a code interpretation server, and offer the service by operating the application program. An RFID reader(110) reads the information of an RFID tag code area or a user data area from the RFID tag(100) entering coverage. A storing part(130) stores a plurality of application programs. A handset(110) recognizes the information for the application program from the information of the read RFID tag code area or user data area, and operates the corresponding application program among the application programs stored in the storing part. The information for the application program stored in the RFID tag code area has a predetermined code format. The information for the application program stored in the user data area has a stand data format.

Abstract:
PURPOSE: An IPv6 Internet address automatically generating method and lookup method using a phone number are provided to allow a phone terminal user to easily access the Internet by using a phone number which has been assigned and conveniently used when an IP protocol is mounted at a phone terminal so as to be used as a host for using an Internet service, and obtains an IP address by generating an IP address of the phone terminal on the basis of a phone number so as for the phone terminal to be operated as a transmitter in an IPv6 communication environment. CONSTITUTION: An IPv6 protocol engine reads a phone number of a terminal(S41). Each decimal number is made to 4 bit binary form by using the phone number constructed as an E.164 form(S42). Since the binary bit stream has the maximum 60 bits or below, a padding operation is performed to add '0' to upper bit digits until it becomes 64 bits from the created bit stream(S43). A 64 bit phone number interface ID is combined with prefix information assigned in an IPv6 protocol operation(S44). An automatic generation of an IPv6 unicast address is completed(S45), and an Internet host transmits an IP packet by using the address.
