This project investigates the design and applications of Autonomous Mobile Underwater SEnsor networks (AMUSE) consisting of a variable number of sonars (sensors) and vehicles that are deployed to perform collaborative tasks over a given area. Underwater acoustic sensor networks (UWA-SNs) are envisioned to enable applications for environmental monitoring of physical and chemical/biological indicators, tactical surveillance, disaster prevention, undersea exploration, and assisted navigation, etc. The major tasks under exploration include UWA-SN self-organization and deployment, self-reconfiguring (MAC, physical layer, and cross-layer design), and mission-aware waveform design/diversity with applications to target recognition, target tracking, and event detection. The AMUSE project is motivated by and targets to solve the following challenges: 1) the sensors in UWA-SN are expensive and mobile, therefore sound self-organization and self-deployment algorithms are needed; 2) waveform design and diversity for UWA-SNs with active sonars are still in its infancy; 3) the transmit and receive data rates are highly asymmetric, which requires new MAC layer design; 4) the underwater channel is impaired by fading, multipath, and doppler shift; 5) the GPS receivers do not work properly in underwater, thus new localization/navigation algorithms are required.The success of the AMUSE project is able to benefit the two areas of urgent national interests: (1) Instrumentation for monitoring/prediction of natural ocean disasters including storm surges, hurricanes, tsunami, etc. (2) Harbor environments and security. In addition, this project can serve as a vehicle to promote cross-disciplinary graduate and undergraduate research and education, and to encourage the participation of under-represented and female students.

该项目调查了自动移动水下传感器网络（AMUSE）的设计和应用，这些传感器网络（AMUSE）由可变数量的声纳（传感器）和部署的车辆组成，这些车辆被部署以在给定区域执行协作任务。 设想水下声学传感器网络（UWA-SNS）可用于对环境监测物理和化学/生物学指标，战术监视，预防灾难，内海探险和辅助导航等。设计/多样性的应用程序可用于目标识别，目标跟踪和事件检测。娱乐项目是由解决以下挑战的动机和目标的：1）UWA-SN中的传感器昂贵且可移动，因此需要自组织和自我部署算法； 2）具有活性声纳的UWA-SNS的波形设计和多样性仍处于起步阶段； 3）传输和接收数据速率高度不对称，这需要新的MAC层设计； 4）水下通道会因褪色，多径和多普勒偏移而受到损害； 5）GPS接收器在水下无法正常工作，因此需要新的本地化/导航算法。Amuse项目的成功能够使紧急国家利益的两个领域受益：（1）监测/预测自然海洋灾害的仪器，包括风暴潮，飓风，飓风，Tsunami等，（2）港口环境和安全环境和安全。此外，该项目可以作为促进跨学科研究生和本科研究和教育的工具，并鼓励代表不足和女学生的参与。
