水下无线传感器网络（UWSNs）有望支持各种民用和军事应用。在超无线传感器网络中，介质访问控制（MAC）协议由于其对网络整体性能的潜在影响而受到广泛关注。与主要依靠无线电波进行通信的地面网络不同，UWSNs利用声波，这对MAC协议的设计提出了新的研究挑战。为了介绍无线传感器网络MAC协议的发展，本文综述了当前最先进的无线传感器网络MAC协议。在早期的发展中，延迟和吞吐量方面的性能的UWSNs一直是MAC层协议设计的主要关注。由于传感器节点一般由电池供电，电池不容易充电，因此设计节能的MAC协议成为一个新的研究热点。在本文中，我们首先描述了水声环境和挑战的MAC协议设计的UWSNs。然后，我们提供了一个比较研究的几种类型的MAC协议，根据目前现有的不同的实现。此外，还将总结开放的研究问题。希望这项调查能激发这一领域更积极的研究。
Underwater Wireless Sensor Networks (UWSNs) are expected to support a variety of civilian and military applications. In UWSNs, Medium Access Control (MAC) protocol has attracted strong attention due to its potentially large impact to the overall network performance. Unlike terrestrial networks, which mainly rely on radio waves for communications, UWSNs utilize acoustic waves, which pose a new research challenge in the design of MAC protocols. To present the development of MAC protocols in UWSNs, this paper surveys the current state-of-the-art MAC protocols for UWSNs. In the early development, the performance in terms of delay and throughput of the UWSNs has been the major concern of the MAC layer protocol design. Later, the design of energy-efficient MAC protocols becomes a new research focus because sensor nodes are generally powered by batteries which are less likely to be recharged. In this paper, we first describe the underwater acoustic environment and the challenges to the MAC protocols design in UWSNs. We then provide a comparative study of several types of MAC protocols according to current existing diverse implementations. Furthermore, open research issues will be summarized. Hopefully, this survey will inspire more active research in this area.
