This project aim at defining, optimizing and implementing a novel underwater sensor network architecture, called SEA-Swarm (Sensor Equipped Aquatic Swarm), that consists of a large number of low cost underwater sensors that operate and move as a group (swarm) with water current and dispersion. The proposed SEA-Swarm architecture will enable a whole new era of observations, monitoring and explorations in the aqueous environment. Such tool will be by its very essence multidisciplinary and is expected to foster a broad collaboration between researchers in networking and communications and other scientific communities, such as environmental sciences, marine biology and coastal surveillance and security. A number of technological challenges shall be addressed by this project, along with the related fundamental research aspects: a new generation of underwater acoustic communications modems is to be designed based on OFDM, achieving unprecedented data rates thanks to Doppler compensation and MIMO space-time signal processing techniques. Cooperative communication protocols, driven by the information theoretic relay channel, are synergistically optimized jointly with a new energy efficient geo-routing algorithm. In essence, all the nodes in a virtual pipe from source to destination cooperate to reliably deliver the message. For reliable data transport, network coding for erasure correction and packet combining for energy efficiency is investigated. Finally, efficient localization schemes based on underwater GPS and nodes with dedicated data-collection functions (data mules) are advocated in order to tackle the mobility and the topology randomness problems due to the swarm nature of the network. The cross-layer design involving the above aspects is validated through a dedicated simulation environment (Aqua-Sim). A cost-effective over-the-water acoustic communication testbed shall be developed by USC in order to provide proof of concept of the basic network algorithms. Finally, an underwater testbed proof of concept is planned in synergy with other existing projects such as MyPond and MySound at U-Conn, and at the UCLA Marina Aquatic Center. The theoretical and experimental work at all three collaborating teams shall involve graduate students and also expose undergraduate students to state-of-the art communication engineering projects, developed in the framework of the above mentioned testbeds.

该项目的目的是定义，优化和实施一种新型的水下传感器网络架构，称为Sea-S-S-Swarm（配备传感器的水生群），该建筑由大量低成本的低成本水下传感器组成，这些低成本的水下传感器（作为一个水流和分散）组成和移动。 拟议的海水建筑将使在水性环境中的观察，监测和探索的全新时代。这种工具将从本质上是多学科的，有望促进网络和通信方面的研究人员与其他科学社区（例如环境科学，海洋生物学以及沿海的监视与安全）之间的广泛合作。 该项目以及相关的基本研究方面应解决许多技术挑战：新一代的水下声学通信调制解调器将基于OFDM设计，得益于多普勒补偿和MIMO时空信号处理技术，实现了前所未有的数据速率。由信息理论继电器渠道驱动的合作通信协议与新的节能地密条算法共同进行了协同优化。 从本质上讲，虚拟管中的所有节点从源到目的地合作以可靠地传递消息。对于可靠的数据传输，研究了用于擦除校正的网络编码，并研究了能源效率的数据包组合。最后，主张基于具有专用数据收集功能（数据mules）的水下GP和节点的有效定位方案，以解决由于网络的群体而引起的移动性和拓扑随机性问题。 涉及上述方面的跨层设计通过专用的模拟环境（Aqua-SIM）验证。加州大学应开发一种经济高效的水声通信测试床，以提供基本网络算法的概念证明。最后，计划与其他现有项目（如Mypond和MySound在U-Conn，以及UCLA Marina Aquatic Center）协同计划。 所有三个合作团队的理论和实验工作均应涉及研究生，并将本科生揭露到上述测试台框架中开发的最先进的传播工程项目。
