ABSTRACT:
Respective nodes N1to N3only detect a carrier, and the node N3sets a random time between a time after a certain period of time t1and a time until a certain period of time t2after the carrier of data D11is gone as a waiting time so as to transmit data within this waiting time. The node N2transmits ACK data D12with respect to the data D11to the node N1before the certain period of time t1after the carrier of the data D11is gone. The node N3detects the carrier of the ACK data D12and again sets a random time after the certain period of time t1until the certain period of time t2to transmit the data.
