Surveys on MAC Protoclo in Ad Hoc Network

在移动Ad Hoc网络中,媒体接入层的性能(Media Access Control,MAC)对整个网络性能的提高具有重要的影响,对该层协议的设计是Ad Hoc面临的关键技术问题。本文在充分调研了国内外Ad Hoc网络MAC协议的研究现状基础上,从信道的分离与接入、拓扑、功率、传输主动方式、业务负载和可扩展性、范围、层次设计等7个方面对现有协议进行分类。并探讨了常见的协议验证分析手段与仿真技术,对衡量MAC层协议的主要性能指标作进一步的分析,最后对MAC层协议研究热点与发展趋势进行综述与展望。In mobile Ad Hoc network,the performance of the MAC( Media Access Control) layer protocol has a significant impact on improving overall network performance. Thus,the design of protocol is the key technical issues facing the Ad Hoc. In this article,we survey and analyze the broadband wireless Ad Hoc network MAC layer protocol. We classify seven key features: channel separation and access,topology,power,transmission initiation,traffic load and scalability,hierarchical design and range. We explore common verification,analysis tools and simulation technology. Then,we make a further analysis of the main performance indicators of MAC layer protocol. Finally,we discusse and reviewe the research hotspot and development trend of MAC layer protocol.海西通信工程技术中心开放课题“无线动态TDMA网络的时隙分配技术”(HXCXJJ2014-012);; 闽南师范大学教改项目“基于物联网的嵌入式系统课程群建设”(JG201519);; 2015年福建省中青年教师教育科研项目“基于对数微分法的多电容同步测量系统研究”(JA15319
