    • A method for generating and registering an identification in a wireless sensor network. The method includes generating an identification of a first layer node; transmitting the identification of the first layer node to a second layer node; detecting whether the identification of the first layer node is duplicated, using the second layer node; if the identification of the first layer node is not duplicated, transmitting a determination message from the second layer node to the first layer node; and determining the identification of the first layer node as a determined identification. The method further includes: if the second layer node does not have a determined identification, re-transmitting the identification of the first layer node after a predetermined period of time has lapsed. Therefore, an automatically identification allocating method using a hierarchical structure can be adopted to enable a distributed management.
    • 一种在无线传感器网络中生成和登记识别的方法。 该方法包括生成第一层节点的标识; 将第一层节点的标识传送到第二层节点; 使用所述第二层节点来检测所述第一层节点的标识是否被复制; 如果第一层节点的标识不被复制,则将确定消息从第二层节点发送到第一层节点; 以及确定所述第一层节点的标识作为确定的标识。 该方法还包括:如果第二层节点不具有确定的标识,则在预定时间段之后重新发送第一层节点的标识已经失效。 因此,可以采用使用层次结构的自动识别分配方法来实现分布式管理。

    • A Radio Frequency Identification (RFID) reader, an RFID tag, and a system and method for identifying a tag using a bit synchronizing signal are disclosed. The system for identifying a tag using a bit synchronizing signal includes: an RFID reader for transmitting a transmission request signal for tag data including a random number generation limit, the bit synchronizing signal, and the number of non-collision bits; and an RFID tag for generating a random bit and a random number within a random number generation limit and for counting the bit synchronizing signal to transmit a response signal through the random bit if the counted bit synchronizing signal coincides with the generated random number and transmitting the tag data to the RFID reader if the number of non-collision bits coincides with the random number. Thus, the identification time per tag can be provided uniformly regardless of the number of RFID tags.
