Current technologies have made it possible for submarines to evade standard sonar detection. Finding solutions to detect intruding submarines therefore becomes important and timely. A viable approach is to deploy magnetic or acoustic sensors in close proximity of possible underwater pathways intruders may pass through. This project seeks to develop a comprehensive theoretical and practical solution to construct undersea sensor networks for intrusion detection. When sensors are randomly deployed, spatial barriers are unlikely to exist, allowing intruders to pass through the bounded 3D space undetected. This motivates the use of mobile sensors to dynamically form sensor barriers. How to minimize the energy consumed by the movement of underwater sensors is a challenging issue. This project tackles the problem via three thrusts: (1) Develop an energy-efficient approach to using mobile sensors to construct a spatial barrier in 3D space; (2) Devise near-optimal practical solutions to reduce computation and communication costs, and develop these algorithms into practical protocols; and (3) Develop simulation modules and test-beds to evaluate the proposed solutions with realistic undersea environment parameters. The project integrates concepts and techniques in auction algorithms, geometry, combinatorial optimization, underwater acoustic communications and networking, software and system development to construct analytical models and practical solutions. The research results are expected to have a substantial impact on the understanding of constructing sensing barriers in underwater environments, and will be integrated into graduate and undergraduate teaching and outreach activities. Efforts will be also proactively pursued to recruit students from under-represented groups to participate in the project.

当前的技术使潜艇有可能逃避标准的声纳检测。因此，寻找检测入侵潜艇的解决方案变得重要和及时。一种可行的方法是在可能的水下途径接近可能通过的磁性传感器上部署磁性传感器。该项目旨在开发一种综合的理论和实用解决方案，以构建海底传感器网络以进行入侵检测。当传感器随机部署时，空间屏障不太可能存在，从而使入侵者可以通过未被发现的有界的3D空间。这促使使用移动传感器动态形成传感器屏障。如何最大程度地减少水下传感器运动所消耗的能量是一个艰巨的问题。该项目通过三个推力解决了问题：（1）开发一种节能方法来使用移动传感器在3D空间中构建空间屏障； （2）设计近乎最佳的实际解决方案，以降低计算和通信成本，并将这些算法开发为实用协议； （3）开发模拟模块和测试床，以使用逼真的海底环境参数评估所提出的解决方案。该项目将概念和技术集成到拍卖算法，几何，组合优化，水下声学通信以及网络，软件和系统开发中，以构建分析模型和实用解决方案。预计研究结果将对在水下环境中构建传感障碍的理解产生重大影响，并将融入研究生和本科教学和外展活动中。还将主动采取努力，从代表性不足的团体中招募学生参加该项目。
