This Small Business Innovation Research (SBIR) Phase I Project supports the development of a low cost, highly efficient, wireless, underwater modem that will lead to new applications for underwater sensor networks. Today, commercially available underwater modems cost several thousand dollars and are typically designed for point-to-point communications using external power sources that are hardwired. Therefore, these modems are not practical for building underwater sensor networks. The objective of this project is to establish the feasibility and direct the future development of a modem that will fill this void in aquatic technology by providing the building blocks for constructing affordable wireless underwater sensor networks. The modem's wireless capability enables measurement data to be continuously transmitted to processing centers on the surface in real-time. The modem's design includes configurable hardware and power management circuitry that minimizes power consumption by automatically adjusting various system parameters in response to environmental conditions. The modem's low cost will not only make sensor networks affordable for a host of new applications, but the high efficiency will also reduce the maintenance costs as the modem will operate for extended periods without the need to recharge the power source.The broader impact/commercial potential of this project is that with the development of the low cost, highly efficient, underwater modem, the concept of dense underwater networks will become a realization for educational institutions, governments and companies around the world. Underwater modems can monitor various aquatic conditions, such as temperature, salinity, nutrient concentration, volatile hydrocarbons, and pathogenic bacteria. By deploying many modems in a small area to create a dense underwater network, a complete and accurate description of aquatic environmental conditions may be obtained. The ability to monitor any aquatic environment in real-time at an affordable cost leads to a host of new applications, such as the monitoring of pollution in lakes and rivers and along shorelines and monitoring the purity of drinking water in municipal reservoirs. For companies, underwater sensor networks would provide effective measurement systems for industrial facilities to monitor their effluent water to ensure their compliance to the environmental and safety regulations that govern their activities. On the global scale, early detection of natural events, such as tsunamis, and man-made disasters, such as oil spills and leaks, can greatly mitigate harm to lives, property and the environment.

该小型企业创新研究 (SBIR) 第一阶段项目支持开发低成本、高效、无线水下调制解调器，这将带来水下传感器网络的新应用。 如今，商用水下调制解调器售价数千美元，通常设计用于使用硬连线的外部电源进行点对点通信。 因此，这些调制解调器对于构建水下传感器网络并不实用。 该项目的目标是确定调制解调器的可行性并指导未来的开发，该调制解调器将通过提供构建经济实惠的无线水下传感器网络的构建块来填补水生技术的这一空白。 调制解调器的无线功能使测量数据能够连续实时传输到地面上的处理中心。 该调制解调器的设计包括可配置的硬件和电源管理电路，可根据环境条件自动调整各种系统参数，从而最大限度地降低功耗。 该调制解调器的低成本不仅使传感器网络能够负担得起许多新应用，而且高效率还将降低维护成本，因为调制解调器可以长时间运行而无需充电。该项目更广泛的影响/商业潜力是，随着低成本、高效、水下调制解调器的开发，密集水下网络的概念将成为世界各地教育机构、政府和公司的实现。 世界。 水下调制解调器可以监测各种水生条件，例如温度、盐度、营养物浓度、挥发性碳氢化合物和致病细菌。 通过在小区域内部署许多调制解调器来创建密集的水下网络，可以获得对水生环境条件的完整且准确的描述。 以可承受的成本实时监测任何水生环境的能力带来了许多新的应用，例如监测湖泊、河流和海岸线的污染以及监测市政水库饮用水的纯度。 对于公司而言，水下传感器网络将为工业设施提供有效的测量系统，以监测其废水，以确保其遵守管理其活动的环境和安全法规。 在全球范围内，及早发现海啸等自然事件和石油泄漏等人为灾害，可以大大减轻对生命、财产和环境的危害。
