Abstract: PURPOSE: A master RFID tag for the administration of physical distribution and a method thereof are provided to enable users to confirm the robbery of products in the middle of circulation steps. CONSTITUTION: A tag reader unit(300) reads information of RFID(Radio Frequency Identification) tag attached to each product stored in a deposit box. A tag information storage unit(310) store the RFID tag information read by the RFID tag. A control unit(330) wirelessly transmits the RFID tag information stored in the tag storage unit to an external RFID reader unit. The tag reader unit is activated by an activation command. The control unit compares the read RFID tag information with the stored RFID tag information.

Abstract: A synchronization method between a reader and a tag are provided to accurately perform the synchronization between a reader and a tag based on the calculation of both clock offset and message delay between the reader and the tag. A reader transmits a first write instruction message to a tag at first time(111), and the tag detects the first write instruction message from the reader at a second time. The tag transmits a first response message corresponding to the first write instruction message to the reader(112), and the reader the second write instruction message including time information for the first time to the tag(113). The tag corrects clock offset by using the difference between the first and second times.

Abstract translation: 提供读取器和标签之间的同步方法，以便基于读取器和标签之间的时钟偏移和消息延迟的计算来精确地执行读取器和标签之间的同步。 读取器在第一时间向标签发送第一写指令消息（111），并且标签在第二时间从读取器检测第一写指令消息。 标签将与第一写入指令消息相对应的第一响应消息发送到读取器（112），并且读取器将包含第一次的时间信息的第二写入指令消息发送到标签（113）。 标签通过使用第一次和第二次之间的差异来校正时钟偏移。

Abstract: 무선 센서 네트워크에서의 선행적 데이터 필터링을 위한 센서노드의 센싱 데이터 전송장치 및 방법이 개시된다. 이 장치 및 방법은 센싱 데이터에 대한 요청 쿼리 및 타이머 파라미터를 수신하고, 수신된 요청쿼리에 따라 센서노드에 감지된 로컬센싱데이터를 검출하고, 요청쿼리를 기초로 타이머 파라미터를 적용한 타이머의 구동시간을 설정하여 설정된 타이머의 구동시간 동안 센서노드의 무선수신범위에 있는 이웃센서노드의 센싱 데이터를 오버히어링하여 로컬센싱데이터가 상기 이웃센서노드의 센싱 데이터와 중복되지 않는 경우에 로컬센싱데이터를 전송한다. 본 발명에 따르면, 데이터 전달 경로를 노드의 에너지 잔량을 고려하여 선정하게 함으로써 노드의 에너지 소진을 분산시켜 네트워크의 수명을 향상시키는 효과가 있다.

Abstract: PURPOSE: An information transmission method of a sensor network is provided to select a short message service of a broadband network or a bearer service according to the size of transmission object information. CONSTITUTION: A gateway receives sensor network information(S310). The gateway filters, analyzes, and classifies the information(S320). The gateway generates an information report message(S330). The gateway selects a transmission service of a relay network according to the size of the information report message(S340). If an SMS(Short Message Service) of broadband network is selected, the gateway edits the information report message as an SMS message(S350,S360).

Abstract: A communication apparatus in wireless sensor network and a method thereof are provided to remove instability of a network, thereby improving stabilization of a sensor network. If a connection setting failure report message is received from an error generating bridge system, a search unit searches a newly used channel and a bridge system(240) performing channel switching. An information management unit replaces information about sensor nodes(210) connected to the searched bridge system with information about sensor nodes newly connected to the searched bridge system through a channel.
