Zusammenfassung:PROBLEM TO BE SOLVED: To prevent a collision between radio communication devices close to one another. SOLUTION: In a state where the radio communication devices are close to one another, one radio communication device becomes a representative node and transmits a representative node advertisement message. When the representative node has received a data packet after transmission of the representative node advertisement message, the representative node transmits a reply acknowledgment message. When a radio communication device which is not decided to be a representative node has become a normal node and has received a representative advertisement message, it transmits a data packet. When it receives an acknowledgment message after transmission of the data packet, transmission of a data packet during the next active period is stopped. COPYRIGHT: (C)2009,JPO&INPIT
