    • A method and an apparatus for assigning a time slot for transmitting a beacon in a wireless sensor network operated in a beacon mode are provided. In the method and apparatus for assigning a time slot according to the present invention, the total time slots assigned to the network are divided into N blocks and a node to which a time slot is exclusively assigned, among nodes to which a specific node is capable of directly and wirelessly transmitting, is selected as a parent node, the network is divided into two or more regions centering the parent node, a block having the time slot assigned to the parent node and adjacent blocks, among the N blocks, are respectively assigned to the regions, a time slot having been yet unassigned, among the time slots belonging to the block assigned to the region to which the specific node belongs among the divided regions, is assigned as the time slot of the specific node.
    • 提供了一种用于在以信标模式操作的无线传感器网络中分配用于发送信标的时隙的方法和装置。 在根据本发明的用于分配时隙的方法和装置中,分配给网络的总时隙在特定节点能够被分配的节点中被划分为N个块和专门分配时隙的节点 被选择为父节点,网络被划分为以父节点为中心的两个或更多个区域,分配有分配给父节点和相邻块之间的时隙的块在N个块中, 分配给分配给特定节点所属于的区域的块的时隙中的尚未分配的时隙被分配为该特定节点的时隙。

    • 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。
