摘要： PROBLEM TO BE SOLVED: To solve the problem, wherein the loads of a processing amount become large when authentication is performed each time connection relation is changed in an ad hoc network, wherein the connection relations among communications terminal equipment are changed rapidly. SOLUTION: When the pieces of the communications terminal equipment have the same common key, mutual authentication is performed by the common key. When the same common key is not provided, the mutual authentication by a public key is performed. Between the pieces of the communications terminal equipment which have performed the mutual authentication, the common key selected by itself and the common key received from the other communications terminal equipment are exchanged with each other and held. At authentication of the communications terminal equipment, when both do not have the common key, one generates the common key and distributes it to the other. When the one has the common key, the common key is generated and distributed to the other. Also, the common key held by the communications terminal equipment that corresponds to a relay node is broadcasted periodically. COPYRIGHT: (C)2006,JPO&NCIPI

The relay node 2 adds new history information to the moving history information of the small size terminal 3 in response to the movement of the small size terminal 3 and transfers it from the relay node 2. The relay node 2 terminates when the monitor end of the small size terminal 3 is detected. When either of a fault of a residence time within a sphere of the relay node of the small size terminal 3 and a release from the network is detected, the moving history information about the small size terminal 3 is informed to a registered emergency time contact destination.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that radio waves interfere between nodes which do not carry out direct communication, and communication quality deteriorates in a radio multi-hop network. SOLUTION: In the multi-hop communication device and its transmission power control method, a node which constitutes the radio multi-hop network exchanges a radio receiving state by transceiving a transmission power control packet with the adjacent node; and radio interferences is reduced by reducing a transmission power to a grade in which communication does not become unstable with the adjacent node to which other direct communication route exists when a radio wave is reached to an adjacent node to which a direct communication route does not exist.
