机会路由(OR)是一种在运行中选择下一跳转发器的很有前途的范例。或因其提高无线网络性能的能力而获得了研究界的极大关注。在OR中，选择一组潜在的节点(候选)来帮助作为下一跳转发器。接收到该分组的每个候选可以继续转发该分组。在OR中，通过使用动态中继节点转发分组，提高了传输可靠性和网络吞吐量。水下传感器网络(UWSN)从环境中收集数据，并将它们传输到海面上的声纳浮标，然后发送到中心进行进一步处理。由于UWSN所共有的水声信道，与无线信道相比，UWSN具有低带宽、高误码率和较长的传播延迟。UWSN的这些特性使它们成为使用OR概念将分组传递到目的地的很好的潜在候选者。本文回顾和比较了为UWSN提出的不同OR协议。我们将现有的方法分类为不同的类别，讨论每类协议的代表性示例，并揭示不同协议所考虑的要求以及它们在其下运行的设计要求和限制。最后，我们讨论了超无线传感器网络未来可能的研究方向。
Opportunistic routing (OR) is a promising paradigm that selects the next-hop forwarder on the fly. OR has gained a lot of attention from the research community for its ability to increase the performance of wireless networks. In OR a potential group of nodes (candidates) is selected to help as the next-hop forwarder. Each candidate that receives the packet can continue forwarding the packet. In OR, by using a dynamic relay node to forward the packet, the transmission reliability and network throughput are increased. Underwater sensor networks (UWSNs) collect data from the environment and transfer them to the sonobuoys on the surface to send them to a center for further processing. Because of the acoustic channels common to UWSNs, they have low bandwidth, high error probability, and longer propagation delay compared to radio channels. These properties of UWSNs make them good potential candidates for using OR concepts to deliver packets to the destination. This article reviews and compares different OR protocols proposed for UWSNs. We classify the existing approaches in different categories, discuss representative examples for each class of protocols, and uncover the requirements considered by the different protocols, as well as the design requirements and limitations under which they operate. Finally, we discuss potential future research directions for UWSNs using the OR paradigm.
