摘要
MANET 是独立的网络自治系统,不依赖于固定主干网络,可提供有效的数据和多媒体通信服务。它使用无线通信技术,所有主机均可以移动。但是众所周知,无线系统是带宽受限系统,信道分配算法至关重要。提高无线资源的使用效率,提高系统的容量和传输质量,一直是研究的重要课题。本文对移动 Ad hoc 网络 MAC 接入控制协议的研究现状进行了综述,揭示了它们的特点和功能,比较了各自的贡献和不足。这些协议涵盖了目前能见到的绝大部分类型的 MAC 协议。最后对 MAC 协议研究的发展方向进行了展望。
A MANET（Mobile Ad-hoc network）is an autonomous non-infrastructure network system of mobile hosts, which are connected with each other via wireless links. It can provide efficient services for data and multimedia applications. However, as we know that the wireless system is a band-limited system, so the channel allocation algorithm is very important. To improve the efficiency, capability and transmission quality of the wireless resource is the key research. This paper provides an overview of various MAC protocols for mobile Ad hoe network by presenting their characteristics and functionalities, and then provides a comparison and discussion of their respective merits and drawbacks, which cover most types of MANET MAC protocols. Finally, the future research directions are outlined.
