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.

目前的技术已经使潜艇有可能避开标准的声纳探测。因此，找到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入侵者可能通过的水下路径附近部署磁传感器或声波传感器。该项目旨在开发一种全面的理论和实践解决方案，以构建用于入侵检测的海底传感器网络。当传感器被随机部署时，空间障碍不太可能存在，允许入侵者穿过有限的3D空间而不被发现。这促使人们使用移动传感器来动态形成传感器屏障。如何最大限度地减少水下传感器运动所消耗的能量是一个具有挑战性的问题。该项目通过三个方面来解决这一问题：(1)开发一种使用移动传感器在3D空间构建空间屏障的节能方法；(2)设计近乎最优的实用解决方案，以降低计算和通信成本，并将这些算法开发为实用协议；以及(3)开发模拟模块和试验台，以评估所提出的解决方案与真实的海底环境参数。该项目整合了拍卖算法、几何、组合优化、水声通信和网络、软件和系统开发方面的概念和技术，以构建分析模型和实用解决方案。预计研究成果将对在水下环境中构建传感屏障的理解产生重大影响，并将被纳入研究生和本科生的教学和推广活动。还将积极努力，从代表性不足的群体中招募学生参加该项目。
