N2 - In this study, we introduce a novel OFDMA-based MAC protocol for underwater acoustic sensor networks. The design approach of this protocol exploits the multi-path characteristics of a fading acoustic channel. The goal is to convert the channel into parallel independent acoustic sub-channels that undergo flat fading. Communication between node pairs within the network is then done using subsets of these sub-channels thus fully utilizing the available limited bandwidth while avoiding interference completely. We derive the mathematical model for optimal subchannel selection. We also present the results of the experiments that we conducted to evaluate the new protocol and we compare these results to those of a MAC protocol that is based on the CDMA scheme.
