    • PURPOSE: A data packet transmission method is provided to improve the stability of transmission by preventing the degradation of total bandwidths. CONSTITUTION: An access point receives a unicast packet transmitted from a predetermined terminal connected to a wireless network (S401). The access point determines a data packet transmission method including rapid transmission speed between the broadcast method or the unicast method based on the number of terminals connected to a wireless network and the access point (S402). The access point transmits broadcast packet converted into the unicast packet to the access point and each terminal connected to the wireless network when the transmission speed of the broadcast method is faster than the unicast method (S403-S404). [Reference numerals] (AA) Start; (BB) Finish; (S501) Receives packets; (S502) Convert into external network address; (S503) Transmit to external interface; (S504) Broadcasting transmission is faster.; (S505) Convert into each connected terminal unicast address; (S506) Transmits to access point interface; (S507) Convert into an original broadcast address
    • 目的:提供数据分组传输方法,通过防止总带宽的恶化来提高传输的稳定性。 构成:接入点接收从连接到无线网络的预定终端发送的单播分组(S401)。 接入点基于连接到无线网络的终端的数量和接入点来确定包括广播方法或单播方式之间的快速传输速度的数据分组传输方法(S402)。 当广播方法的传输速度比单播方式更快时,接入点将转换成单播分组的广播分组发送到接入点和连接到无线网络的每个终端(S403-S404)。 (附图标记)(AA)开始; (BB)完成; (S501)接收包; (S502)转换为外部网络地址; (S503)发送到外部接口; (S504)广播传输更快; (S505)转换为每个连接的终端单播地址; (S506)发送到接入点接口; (S507)转换为原始广播地址

    • PURPOSE: Multi-hop radio communications method of the tree-based considering the node transition is provided to supply routing protocol applied to the network of high-mobility. CONSTITUTION: A general node has a communication state of alone of a plurality of general nodes(100). The general node sets communication establishment information based on a sink node(200) in which the general node generates a connection reply signal, the communication state and the communication level of the general node. The general node updates the communications establishment information based on the connection reply signal received from a parent node. The general node transmits data to the other general node or a server(300) based on an updated communication setting information.
    • 目的:考虑节点转移的树型多跳无线电通信方式,提供应用于高移动性网络的路由协议。 构成:通用节点具有多个通用节点(100)中的单独的通信状态。 通用节点根据其中通用节点生成连接应答信号,通信状态和通用节点的通信级别的汇聚节点(200)来设置通信建立信息。 通用节点根据从父节点接收到的连接应答信号更新通信建立信息。 一般节点基于更新的通信设置信息向另一个通用节点或服务器(300)发送数据。
