    • A method and apparatus for grouping wireless access points and re-grouping access points separated from a group in order to construct a clear and efficient transmission connection channel in an extended wireless LAN architecture are provided. Accordingly, a grouped mobile node determines disconnection of a connection channel to the group, and if the connection channel is disconnected, the mobile node searches for a connection channel to the existing group or a new group to re-subscribe thereto, so that all the mobile nodes can always be in a grouped state. As a result, it is possible to prevent broadcast storm in which broadcasted frames are repetitively transmitted along a loop in an extended wireless LAN architecture.
    • 提供了一种用于分组无线接入点并重新分组与组分离的接入点以便构建扩展无线LAN架构中的清晰且有效的传输连接信道的方法和装置。 因此,分组的移动节点确定到组的连接信道的断开,并且如果连接信道被断开,则移动节点搜索到现有组或新组的连接信道以重新订阅,以便所有 移动节点总是处于分组状态。 结果,可以防止在扩展的无线LAN架构中沿着循环重复地发送广播的帧的广播风暴。

    • An apparatus and method for routing on a mobile ad-hoc network are provided. The apparatus and method allow each node in a network to: measure a packet transmission rate to a neighboring node using a signal-to-noise ratio (SNR); measure variation in the number of nodes due to their insertion or deletion; distribute relative packet transmission time relative to the SNR, which is measured using the packet transmission rate; and determine a routing path using the stored relative packet transmission time relative to the SNR. The apparatus includes a transceiver that receives a reply packet from a neighboring node, a measuring unit that uses the reply packet to measure movement of the neighboring node and a relative packet transmission time thereto, and a routing path determination unit that uses the relative packet transmission time to determine a routing path in the network.
    • 提供了一种用于在移动自组织网络上进行路由的装置和方法。 该装置和方法允许网络中的每个节点使用信噪比(SNR)来测量到相邻节点的分组传输速率; 测量由于插入或删除而导致的节点数量的变化; 分配相对于使用分组传输速率测量的SNR的相对分组传输时间; 并且使用所存储的相对于所述SNR的相对分组传输时间来确定路由路径。 该装置包括从相邻节点接收应答分组的收发机,使用应答分组来测量相邻节点的移动的测量单元和相对分组传输时间,以及使用相对分组传输的路由路径确定单元 确定网络中的路由路径的时间。
