在本文中，我们研究了三种介质访问控制（MAC）协议（CSMA， T-Lohi和DACAP）的性能，代表简单，中间和完全协商的协议，在两次海上战役中访问水声信道。在2010年9月的北约ACommsNet10实验期间，在皮亚诺萨岛周围水域进行了各种测试，在2013年北约CommsNet13实验期间，在Palmaria岛海岸进行了各种测试。使用不同类型的应用程序负载和通信设备来研究各种协议在不同传输速率和引入开销下的性能。还探讨了建立更稳定和可靠的通信联系以及建立一个高度动态的通信渠道的问题。收集到的结果表明，没有单一的解决方案对所有可能的场景和配置都是最好的，不同的上下文需要选择不同的协议。这凸显了了解海上各种协议在各种条件下的性能，设计新颖和自适应方案的重要性，这些方案能够以高效和有效的方式对网络和通信通道中可能发生的变化做出反应。
In this paper, we investigate the performance of three medium access control (MAC) protocols (CSMA, T-Lohi, and DACAP) representing simple, intermediate, and fully negotiated protocols, to access the underwater acoustic channel, during two at-sea campaigns. Various tests were conducted in the waters surrounding Pianosa island during the NATO ACommsNet10 experiment in September 2010 and off the coast of the Palmaria island during the NATO CommsNet13 experiment in 2013. Different types of application loads and communication devices have been used to investigate the performance of the various protocols under different transmission rates and introduced overhead. The presence of more stable and reliable communication links and of a highly dynamic communication channel has also been explored. The collected results show that there is no single solution that is best for all the possible scenarios and configurations and that the selection of different protocols is required for different contexts. This highlights the importance of understanding the performance of each protocol at sea, under various conditions, to design novel and adaptive schemes, which are able to react in an efficient and effective way to possible changes in the network and in the communication channel.
