水下设备的无线联网系统正在成为许多商业、科学和军事应用的基础。尽管在过去的几年里，水下无线网络技术越来越受到关注，但仍然受到重大限制，包括严重的硬件依赖。在本文中，我们介绍了SEANet项目，NSF资助的努力，旨在开发新一代的可编程平台和网络测试平台，以实现可编程的水下物联网（IOUT）的愿景。SEANet将基于基于开放式架构的新软件定义平台，以实现在硬件和软件中定义、添加、更新和交换新组件的灵活性。SEANet的设计目的是支持数据速率至少一个数量级高于现有的商业平台在短期和中等范围的链接。此外，SEANet项目将探索新的定制设计的超宽带微机电系统（MEMS）换能器的设计，该换能器允许在更宽的声学带宽（即，0.01.- 2 MHz）。我们提出了一套初步的实验表明，SEANet可以优于现有的软件定义无线电SDR基于声学调制解调器的基础上，商业现货（COTS）SDR平台。我们还展示了SEANet的实时重构能力和MEMS传感器的初步性能。
Wirelessly networked systems of underwater devices are becoming the basis of many commercial, scientific, and military applications. In spite of increased attention in the last few years, underwater wireless networking technology still suffers from major limitations, including severe hardware dependence. In this paper, we introduce the SEANet Project, an NSF-funded effort that aims at developing a new generation of programmable platforms and a networking testbed to enable the vision of a programmable Internet of Underwater Things (IoUT). SEANet will be based on new software-defined platforms based on an open architecture to enable the flexibility to define, add, update, and swap new components in both hardware and software. SEANet is designed to support data rates at least one order of magnitude higher than existing commercial platforms over short and moderate range links. Moreover, the SEANet project will explore the design of new custom-designed ultra-wide band Microelectromechanical systems (MEMS) transducers that allow operating over much wider acoustic bandwidth (i.e., 0.01.-2 MHz) than possible with bulk piezoelectric transducers. We present a set of preliminary experiments showing that SEANet can outperform existing software-defined radio SDR-based acoustic modems based on a commercial off-the-shelf (COTS) SDR platforms. We also demonstrate the real-time reconfiguration capability of SEANet and preliminary performance of the MEMS transducers.
