一种用于水声通信网的多址接入协议

A MAC Protocol for Underwater Acoustic Networks

海洋信息获取、环境监测、海岸防御等各种应用都迫切需要研究开发高效可靠的水声通信网.针对水声信道条件恶劣、频带受限的特点,提出了一种基于RTS/CTS的多信道接入协议,该协议利用公用码字进行RTS-CTS交换实现业务信道的预约,提高了网络效率.仿真实验结果表明,该协议具有较好的网络性能.

There exists an increasing demand for reliable, high capacity underwater acoustic networks （UANs）. Application interests indude oceanographic information gathering, environmental monitoring, and coastal defense. A multi-channel media access control （MAC） protocol used for underwater acoustic channel which improves the network efficiency by using RTS-CTS exchange, is presented. Simulation tests on opnet modeler show that, its network communication performance is satisfactory.
