Due to the long propagation delay of acoustic waves and limited available bandwidth of the underwater acoustic channels, it takes a long delay for the handshaking between the transmitting/receiving nodes to avoid the data/control packets collision. This will decrease the channel utilization ratio, and increase the power consumption of the nodes. In this paper, a reversal multichannel media access control protocol using blind source separation for underwater acoustic sensor networks is presented. Compared with existing multichannel protocols, the proposed MAC protocol adds channel reservation information in handshaking packet, and uses the blind source separation to deal with the control packets collision. It makes the channel reservation will be finished before the current data transmission ending. At the end of this paper, the simulation results show that the network throughput and energy consumption of the proposed MAC protocol are much better than that of multichannel MACA on the heavy network traffic condition.
