Unlike terrestrial radio frequency communication, acoustic waves are major communication means in underwater networks. Unfortunately, incur long propagation delays that must be considered the media access control (MAC) design to achieve a high throughput. Another reason for low throughput is almost all modems operate under half-duplex mode. For increasing throughput, several full-duplex proposed. However, most current MAC protocols designed not suited modems. Toward proper approach, this...
