到目前为止，水下声学网络（UAN）严重依赖于商业上可用的声学调制解调器。虽然商用调制解调器通常能够支持特定应用，但它们通常不够灵活，无法满足下一代UAN的要求，下一代UAN需要能够基于环境和应用条件实时调整其通信和网络协议。为了满足这些需求，我们提出了SEANet（软件定义的声学网络），一个模块化的，不断发展的软件定义的框架UAN设备，提供了必要的灵活性，以适应和满足不同的应用程序和系统的要求，通过一组定义良好的功能，在物理，数据链路，网络和应用层的网络协议栈。SEANet基于结构化模块化架构，可在不同层进行实时重新配置，为部署新协议设计和增强提供灵活的平台，并确保软件可移植性以实现平台独立性。此外，我们提出了一个低成本，完全可重构的水下传感平台，实现了SEANet框架的原型，并讨论了水箱测试的性能评估结果。
As of today, Underwater Acoustic Networks (UANs) are heavily dependent on commercially available acoustic modems. While commercial modems are often able to support specific applications, they are typically not flexible enough to satisfy the requirements of next-generation UANs, which need to be able to adapt their communication and networking protocols in real-time based on the environmental and application conditions. To address these needs, we present SEANet (Software-dEfined Acoustic Networking), a modular, evolving software-defined framework for UAN devices that offers the necessary flexibility to adapt and satisfy different application and system requirements through a well-defined set of functionalities at the physical, data-link, network, and application layers of the networking protocol stack. SEANet is based on a structured modular architecture that enables real-time reconfiguration at different layers, provides a flexible platform for the deployment of new protocol designs and enhancements, and ensures software portability for platform independence. Moreover, we present a prototype of a low-cost, fully reconfigurable underwater sensing platform that implements the SEANet framework, and discuss performance evaluation results from water tank tests.
