    • A node for self localization, a clustering method using the same, and a localization method are provided. The node, which is located in a specific space so as to constitute a sensor network, includes a location information messaging unit which receives one or more location information messages including information on spatial locations of one or more neighboring nodes in the sensor network from the neighboring nodes in the sensor network; a distance calculator which calculates a first distance to the neighboring node on the basis of the location information included in the received location information messages and calculates a second distance to one or more neighboring nodes on the basis of the received time or intensity of the message on the location information; and a clustering unit which forms clusters of the node and a plurality of neighboring nodes in which the difference between the first and second distances is less than a predetermined threshold.

    • Provided are a coordinator in a wireless sensor network (WSN) which can improve transmission performance and prevent data loss, and a method of operating the coordinator. The method includes: scanning a transmitted beacon and storing information on a channel included in the beacon; when it is determined that a home channel communicating with a parent node is in an inactive mode on the basis of the information on the channel, in synchronization with the activation of another channel of the same hierarchical level as that of the home channel, activating a home channel communicating with a child node and communicating with the child node; and communicating with the child node through an auxiliary channel that has a frequency band different from those of the home channel communicating with the child node and home channels of other nodes and is always in an active mode.
    • 提供了可以提高传输性能并防止数据丢失的无线传感器网络(WSN)中的协调器,以及操作协调器的方法。 该方法包括:扫描发送的信标并将信息存储在信标中包括的信道上; 当确定与父节点通信的归属信道基于信道上的信息处于非活动模式时,与激活与归属信道相同等级的另一信道同步,激活 家庭频道与子节点通信并与子节点通信; 并且通过辅助信道与子节点进行通信,所述辅助信道具有与其他节点的子节点和家庭信道通信的归属信道的频带不同的频带,并且始终处于活动模式。

    • Provided is a method and system for hierarchically communicating information between a user and an information providing server that provides information requested by the user. The system includes at least one sensor node, upon receipt of an information request message sent by the user through a terminal, searching for information corresponding to the information request message in a first cache mounted therein and sending the information request message if the corresponding information is not found in the first cache, and a cache server, upon receipt of the information request message from the at least one sensor node, searching for the information corresponding to the information request message in a second cache mounted therein, sending the information request message to the information providing server if the corresponding information is not found in the second cache, receiving the corresponding information, transmitting the received information to the sensor node, and updating the second cache.
    • 提供了一种用于在用户和提供用户请求的信息的信息提供服务器之间分层传送信息的方法和系统。 该系统包括至少一个传感器节点,当接收到用户通过终端发送的信息请求消息时,在安装在其中的第一高速缓存中搜索对应于该信息请求消息的信息,并且如果相应的信息是 在第一高速缓存中没有找到缓存服务器;以及缓存服务器,在从所述至少一个传感器节点接收到所述信息请求消息时,在安装在其中的第二高速缓存器中搜索对应于所述信息请求消息的信息,将所述信息请求消息发送到 信息提供服务器,如果在第二高速缓存中没有找到对应的信息,则接收对应的信息,将所接收的信息发送到传感器节点,并更新第二高速缓存。
