    • On ad hoc networks in which connection relationships among communication terminals constantly change, the processing load increases when authentication is performed each time a connection relationship changes. According to this invention, when communication terminals possess the same common key, mutual authentication is conducted with that common key, and when communication terminals do not possess the same common key, mutual authentication is conducted with a public key. Communication terminals that conducted mutual authentication exchange and retain a common key that they selected and common keys received from other communication terminals. When neither communication terminal possesses a common key at authentication, one terminal creates a common key and distributes it to the other terminal, and when one terminal has a common key it creates that common key and distributes it to the other terminal. Further, a common key possessed by a communication terminal corresponding to a relay node is broadcast periodically.
    • 在通信终端之间的连接关系不断变化的自组织网络上,当每次连接关系改变时进行认证时,处理负载增加。 根据本发明,当通信终端具有相同的公共密钥时,用该公共密钥进行相互认证,当通信终端不具有相同的公共密钥时,用公开密钥进行相互认证。 进行相互认证的通信终端交换并保留所选择的公共密钥和从其他通信终端接收的公共密钥。 当通信终端在认证时都没有公共密钥时,一个终端创建一个公用密钥并将其分配给另一个终端,当一个终端具有公共密钥时,它创建公用密钥并将其分配给另一个终端。 此外,周期性地广播由对应于中继节点的通信终端拥有的公共密钥。

    • One objective of the present invention is to determine a location for a relay terminal in a radio network, without preparatory surveying a radio status and to arrange the relay terminal at the location. Another objective is to provide a method for retrieving the arranged relay terminal. When a relay terminal is to be arranged, the relay terminal transmits a survey packet to examine the quality of communication with a communication terminal or other relay terminal. Where a location is appropriate, the relay terminal gives a notice. The arranged terminal relays communication. Further, when the relay terminal is to be retrieved, the relay terminal carried by a user transmits a retrieval packet to the arranged relay terminal, which notifies the user of its presence by light, sounds, or returning a packet. In this manner, a single relay terminal provides functions of arrangement, relay and retrieval.
    • 本发明的一个目的是确定无线网络中的中继终端的位置,而无需准备测量无线电状态并将中继终端布置在该位置。 另一个目标是提供一种用于检索所布置的中继终端的方法。 当要布置中继终端时,中继终端发送一个调查分组以检查与通信终端或其他中继终端的通信质量。 在适当的位置,中继终端发出通知。 安排的终端中继通信。 此外,当要检索中继终端时,由用户携带的中继终端向所配置的中继终端发送检索分组,该消息通知用户其存在光,声音或返回分组。 以这种方式,单个中继终端提供布置,中继和检索的功能。
