In underwater acoustic sensor networks,a shorter link can provide more bandwidth than a longer link. The multirate underwater acoustic sensor networks model can select transmission rates dynamically according to different link length,which improves the bandwidth utilization. A handshaking-based negotiation mechanism is proposed to solve the transmission rates negotiation problem in multirate underwater acoustic sensor networks. This mechanism is applied to networks where nodes do not know the link length,which decreases end-to-end delay and energy consumption per bit under the premise that network connectivity is ensured. The simulation results show that this kind of negotiation mechanism can effectively improve the network performance of underwater acoustic sensor networks.
