方法和算法的安全合作的一组自主的移动的水下传感器，通过声学通信网络连接，在监视和巡逻应用。特别是，这项工作提出了一种合作的算法，其中的移动的水下传感器（安装在自主水下航行器AUV）响应简单的本地规则的基础上，可用的信息来执行的使命，并保持与网络的通信链路（行为的方法）。该算法本质上是鲁棒的：在车辆之间失去通信的情况下，覆盖性能（即，使命目标）被降级但没有丢失。随之而来的优雅降级形式也提供了针对拒绝服务的反应措施。合作算法依赖于这样一个事实，即来自其他传感器的可用信息，虽然不一定是完整的，但是值得信赖的。为了确保可信度，已经设计了一个安全套件，专门面向水下场景，特别是减少通信开销的目标，在消息的数量和大小方面的安全性。本文给出了安全套件和合作算法之间的集成的实施细节，并提供了在UAN项目海上试验期间收集的系统性能的统计数据在特隆赫姆，挪威，在2011年5月。
Methodologies and algorithms are presented for the secure cooperation of a team of autonomous mobile underwater sensors, connected through an acoustic communication network, within surveillance and patrolling applications. In particular, the work proposes a cooperative algorithm in which the mobile underwater sensors (installed on Autonomous Underwater Vehicles—AUVs) respond to simple local rules based on the available information to perform the mission and maintain the communication link with the network (behavioral approach). The algorithm is intrinsically robust: with loss of communication among the vehicles the coverage performance (i.e., the mission goal) is degraded but not lost. The ensuing form of graceful degradation provides also a reactive measure against Denial of Service. The cooperative algorithm relies on the fact that the available information from the other sensors, though not necessarily complete, is trustworthy. To ensure trustworthiness, a security suite has been designed, specifically oriented to the underwater scenario, and in particular with the goal of reducing the communication overhead introduced by security in terms of number and size of messages. The paper gives implementation details on the integration between the security suite and the cooperative algorithm and provides statistics on the performance of the system as collected during the UAN project sea trial held in Trondheim, Norway, in May 2011.
