现有的水声组网平台在很大程度上是基于僵化的硬件和软件体系结构，可以支持大多数点对点、低数据速率、延迟容忍的应用。大多数商业设备既不能提供足够的数据速率，也不能提供必要的灵活性来支持未来的水下网络应用和系统。本文讨论了一种新的高数据速率的软件定义的水声组网平台SEANET G2，它能够支持更高的数据速率(预计在短距离链路上有兆比特/S的数据速率)、频谱敏捷性和硬件/软件灵活性，以支持分布式联网监控操作。文章介绍了新平台的主要架构选择，以及一些初步的性能评估结果。在受控的实验室环境中演示了兆比特/S量级的数据速率，据我们所知，首次在短水平链路(例如，10m)上的海试中获得了522kbit/S的数据速率，误码率低于10−3。
Existing underwater acoustic networking platforms are for the most part based on inflexible hardware and software architectures that can support mostly point-to-point, low-data-rate, delay-tolerant applications. Most commercial devices do not provide neither the sufficient data rates nor the necessary flexibility to support future underwater networking applications and systems. This article discusses a new high-data rate software-defined underwater acoustic networking platform, SEANet G2, able to support higher data rates (megabit/s data rates are foreseen over short range links), spectrum agility, and hardware/software flexibility in support of distributed networked monitoring operations. The article reports on the main architectural choices of the new platform, as well as some preliminary performance evaluation results. Data rates in the order of megabit/s were demonstrated in a controlled lab environment, and, for the first time to the best of our knowledge, data rates of 522kbit/s where obtained in sea trials over short horizontal links (e.g., 10 m) for a BER lower than 10−3.
