摘要： PROBLEM TO BE SOLVED: To provide an IP network apparatus capable of facilitating the resetting of basic information such as an IP address or the like, and to provide an IP network system provided with the IP network apparatus.
SOLUTION: The base station 12 is a base station 12 to which the IP address is set, and is provided with a processing part 20 for performing processing based on a received packet. The processing part 20 confirms the transmission destination of the packet included in the received packet, and when confirming that the transmission destination is itself, rewrites the IP address set to itself with the IP address included in the packet on condition that a specified code is included in the packet. By the base station 12, the IP address is easily and correctly set again even when the IP address of the base station 12 is erroneously set due to the human error of a system manager.

摘要： PROBLEM TO BE SOLVED: To reduce traffic volume without affecting a packet arrival rate.
SOLUTION: A receiver 30 receives a signal which is a signal reported from a radio device 10 as a transmission source and includes a packet signal indicating the position of the radio device 10. A relay processing unit 38 performs relay processing, after a delay time set up in proportion to a distance detected by a distance detector 36 after receiving the signal reported from the radio device by the receiver 30 passes. A relay processor 38 stops the relay processing after the delay time passes, when the same packet signal as the packet signal received by the receiver 30 is received before the delay time passes.

摘要： PROBLEM TO BE SOLVED: To provide a reactive routing communications device for configuring a stable communication path with little change in path, in inter-vehicle communication.
SOLUTION: In addition to information elements of a conventional reactive routing pathfinding packet, a packet-relaying vehicle address column, an east/west direction speed column, a south/north direction speed column and an evaluation value column are provided. When the received pathfinding packet is relayed, a relative speed value is added with an immediately front vehicle, calculated by a setting means 6 in the evaluation value column of the packet received for a predetermined standby time, since the packet was first received. A relay means 5 updates the packet whose value in the evaluation value column is the smallest among the packets stored in a queue 3 to the packet-relaying vehicle address column to an address of the own vehicle, the east/west direction speed column to the east/west direction speed of the own vehicle, and the south/north direction speed column to the south/north direction speed of own vehicle. They are broadcast via a transmitting means 9 and an antenna 10.

摘要： PROBLEM TO BE SOLVED: To provide a radio communication system that can avoid or relax a compressed band by a hello packet.
SOLUTION: The system transmits only own station information as the hello packet as a rule (204, 206). When a participation station is detected (220) on the basis of the hello packet received from another station and information on a database 212 in its own station or a retire station is detected, the hello packet including adjacent station information is transmitted (210, 214, 204). When all adjacent station information including all participation stations and retire stations detected by its own station has been received between preceding transmission of the hello packet and the present is received by the hello packet from another station (230), difference information with respect to all the adjacent station information is generated (232). When a first hello packet is transmitted after detection of participation and retire stations and the difference information is generated after the preceding transmission (208), the hello packet including the difference information is sent (210, 206), and when not transmitted, the hello packet including all the adjacent station information is sent (214, 206).
