摘要: 移动自组织网络(mobile Ad Hoc network,MANET)具有节点频繁移动、拓扑动态变化的特点,媒体接入控制(media access control,MAC)协议作为节点访问无线信道资源时所遵循的基本通信协议,对网络性能至关重要。随着应用任务的多样化和服务质量(quality of service,QoS)需求的提升,设计能够在MANET这种动态环境中保持较好网络性能的自适应MAC协议成为关键。概述了MANET的网络特性和基本MAC协议分类,分析了MAC协议设计时面临的挑战;从不同的MAC协议改进基础出发,阐述了近年来应用于复杂网络环境的自适应MAC协议,并归纳对比了这些协议的特点、性能及局限性等;总结了自适应MAC协议的研究进展,对下一步的研究方向进行了展望。

Abstract: Mobile Ad Hoc Network(MANET) has the characteristics of frequent node movement and dynamic topology, and the media access control(MAC) protocol, as the basic communication protocol followed by nodes to access wireless channel resources, is critical to network performance. With the diversification of application tasks and the increasing demand for quality of service(QoS), it is critical to design an adaptive MAC protocol that can maintain good performance in a dynamic environment such as MANET. Firstly, the network characteristics and basic MAC protocol classification of MANET are summarized, and the challenges faced in MAC protocol design are analyzed. Then, starting from the improvement basis of different MAC protocols, the adaptive MAC protocols applied to complex network environments in recent years are expounded, and the characteristics, performance and limitations of each protocol are summarized and compared. Finally, the research progress of adaptive MAC protocol is summarized, and the next research direction is prospected.
