Medium Access Control (MAC) protocol plays an important role in full-duplex wireless networks. Theoretically, full-duplex communications have this ability to increase the capacity of traditional half-duplex wireless systems by up to twice. However, designing and implementing an efficient MAC protocol is a central issue in this way. Increasing throughput, collision avoidance, and fairness are common challenges in designing an efficient full-duplex MAC protocol. After giving a short introduction to the general classification of traditional MAC protocols, IEEE 802.11 MAC protocol, and the identified challenges of full-duplex communications in wireless networks, this review paper provides a comprehensive survey of current major MAC protocols for full-duplex wireless communications and classifies them in to three categories i.e. distributed wireless local area networks, centralized wireless local area networks, and other types of networks. This paper also explores and gives a comparative analysis of current full-duplex MAC protocols with stating their advantages and disadvantages as well as comparing them one with another.

介质访问控制（MAC）协议在全双工无线网络中扮演重要角色。从理论上讲，全双工通信具有将传统半双工无线系统的容量增加两倍的能力。但是，以这种方式设计和实现有效的MAC协议是一个中心问题。在设计有效的全双工MAC协议时，提高吞吐量，避免冲突和公平是常见的挑战。在简要介绍了传统MAC协议的一般分类，IEEE 802.11 MAC协议以及已确定的无线网络中全双工通信的挑战之后，本文将对当前用于全双工无线通信的主要MAC协议进行全面调查。并将它们分为三类，即 分布式无线局域网，集中式无线局域网和其他类型的网络。本文还探索并给出了当前全双工MAC协议的比较分析，阐明了它们的优缺点，并进行了比较。
