<P>PROBLEM TO BE SOLVED: To relax traffic, and to reduce loads by reducing the number of times for transmitting information, when a transmission node transmits the similar information to a plurality of nodes in a high-density radio network. <P>SOLUTION: A transmission PC determines whether a reception PC connected to the radio network is in an arbitrary state, creates a distribution list in which the reception PC that is scheduled to transmit information is mentioned (S1), and directly transmits the information to the reception PC without going through other reception PCs only once with the maximum output (S2). The reception PC determines whether a state mentioned in the information agrees with an own state and transmits an ACK signal to the transmission PC when they agree (S3). The transmission PC erases a record corresponding to the reception PC of the transmission source from the distribution list (S6) when receiving the ACK signal (YES for S5), and when the reception PC that is scheduled to transmit information remains in the distribution list (YES for S7), transmits the similar information to the reception PC in a unicast communication method (S8). <P>COPYRIGHT: (C)2007,JPO&INPIT |
