近年来，人们对发展水声传感器网络的兴趣迅速增长，它可以用于监测水环境的科学探索，商业开发和海岸线保护。水环境的复杂性和网络场景的复杂性要求水下网络的新解决方案，并需要在协议套件的每个级别上进行大量的研究工作。在这个项目中，一个新的方法，使用表面无线电，以帮助水下声学。本文提出了一种适用于浅海几何动力学应用的无线电和声学综合分布式系统。该系统具有许多优点，例如高能效，高可靠性和低端到端延迟。解决方案包括三个关键任务，即降低计算复杂度的分布式网关部署算法、与水下传感器网络联合优化以提高整个网络性能以及面向移动的网络场景的动态网关部署。一组协议和算法也是可交付成果的一部分。这些解决方案和算法有助于智力价值。除了研究意义之外，该项目还在三个方面对教育产生了重要影响，包括支持研究生的高级研究，支持本科生，女性和其他代表性不足的群体，以及促进跨部门教师和学生之间的多学科合作。

Recently there has been a rapid growing interest in developing underwater acoustic sensor networks, which can be used in monitoring aquatic environments for scientific exploration, commercial exploitation, and coastline protection. The complexity of aquatic environments and the sophistication of the networking scenarios demand new solutions for underwater networks, and require significant research efforts at every level of the protocol suite. In this project, a novel approach of using surface radios to help underwater acoustics is employed. An integrated hybrid radio and acoustic distributed system for geometrydynamic shallow water applications is developed. This system has numerous benefits such as high energy efficiency, high reliability and low end-to-end delay. Deliverables include solutions to three critical tasks, namely, distributed gateway deployment algorithms to reduce computational complexity, joint optimization with underwater sensor network to improve the whole network performance, and dynamic gateway deployment for mobile network scenarios. A set of protocols and algorithms are also a part of the deliverables. These solutions and algorithms contribute toward the intellectual merit. Beyond the research significance, this project has important impact on education on three fronts including supporting graduate students in their advanced research, supporting undergraduates, women and other under-represented groups, and promoting multi-disciplinary collaborations among faculty and students across departments.
