This paper develops and compares different sensor network architecture designs that can be used for monitoring underwater pipeline infrastructures. These architectures are underwater wired sensor networks, underwater acoustic wireless sensor networks, RF (radio frequency) wireless sensor networks, integrated wired/acoustic wireless sensor networks, and integrated wired/RF wireless sensor networks. The paper also discusses the reliability challenges and enhancement approaches for these network architectures. The reliability evaluation, characteristics, advantages, and disadvantages among these architectures are discussed and compared. Three reliability factors are used for the discussion and comparison: the network connectivity, the continuity of power supply for the network, and the physical network security. In addition, the paper also develops and evaluates a hierarchical sensor network framework for underwater pipeline monitoring.
本文开发并比较了可用于监测水下管道基础设施的不同传感器网络架构设计。这些架构包括水下有线传感器网络、水下声无线传感器网络、射频（RF）无线传感器网络、集成有线/声无线传感器网络以及集成有线/RF 无线传感器网络。本文还讨论了这些网络架构的可靠性挑战和增强方法。讨论和比较了这些架构之间的可靠性评估、特性、优点和缺点。讨论和比较中使用了三个可靠性因素：网络连接、网络电源的连续性以及物理网络安全性。此外，本文还为水下管道监测开发和评估了一种分层传感器网络框架。
