This proposal focuses on the networking of free-floating underwater observation systems through acoustic communications. These free-floating explorers drift along with the ocean currents and offer scientists a way to observe organisms and processes in their own frame of reference. The advantage of networking them together is that it allows information to be relayed to users in real time and perform coordinated tasks. Intellectual Merit: The intellectual goal is to create new networking protocols that are tailored towards the unique challenges of acoustic underwater networks of these free-floating explorers. This includes self-localization methods that allow devices to efficiently track their continuously-changing physical position, while minimizing the associated energy cost. Novel routing protocols will be developed to relay information to the users within the unique constraints of the system. In addition to simulation studies and analytical analysis, the new protocols will also be tested in a real-life deployment at sea. Multiple drogues, equipped with sensors and a buoyancy control actuator, will be assembled to provide an experimental platform for testing the new ideas. Broader Impacts: This project will have broader impacts on many levels. A group of autonomous drogues has the potential to vastly increase the space/time sampling of oceanic processes compared to what is currently possible with other techniques. This is paramount to progress in the field of oceanography. In addition, the results from the project will be integrated into the curriculum on underwater acoustics and on wireless networking at UCSD. The collaboration initiated in this proposal will also be carried forward into extended joint research, which will benefit researchers and students in both fields due to its diverse and inter-disciplinary nature. Through the Center for Educations Outreach Connections at Scripps, the results and overall vision can be disseminated to the public, via school presentations or exhibits.

该提案重点是通过声学通信的自由浮动水下观察系统的网络。这些自由浮动的探险家与洋流一起漂移，并为科学家提供了一种观察自己参考框架的生物和过程的方式。将它们联网的优势在于，它允许将信息实时传输到用户并执行协调的任务。知识分子的优点：智力目标是创建新的网络协议，这些协议是针对这些自由浮动探险家的声学水下网络独特挑战而定制的。这包括自定位方法，允许设备有效地跟踪其不断变化的物理位置，同时最大程度地减少相关的能源成本。将开发新的路由协议以在系统的唯一约束中传达给用户。除了模拟研究和分析分析外，新方案还将在海上现实生活中进行测试。配备传感器和浮力控制执行器的多个Drogues将组装，以提供测试新想法的实验平台。更广泛的影响：该项目将对许多层面产生更广泛的影响。与其他技术相比，一组自主的drogues有可能大大增加海洋过程的空间/时间抽样。这对于海洋学领域的进展至关重要。此外，该项目的结果将集成到UCSD的水下声学和无线网络上的课程中。在该提案中启动的合作也将进行扩展的联合研究，该研究将使其多样化和学科的性质受益于两个领域的研究人员和学生。通过Scripps的教育中心外展联系中心，可以通过学校演讲或展览将结果和整体愿景传播给公众。
