摘要： 介绍基于定向天线的MAC协议，根据这些协议所涉及到的天线模型、发射接收模式以及使用定向天线所面临的定向隐藏终端和聋节点问题等，对Ad hoc网络中配置定向天线的相关MAC协议、问题及其解决办法进行分析比较。结果表明，基于定向天线的MAC协议能提高Ad hoc网络的整体性能。

关键词: Ad hoc网络, 定向天线, MAC协议

Abstract: This paper discusses the antenna models, the ways of antennas transmission and receiving, and the problems using the directional antennas in Ad hoc networks. It summarizes the MAC protocols in Ad hoc networks with directional antennas, the problems and the solutions. Result shows that MAC protocols in Ad hoc networks with directional antennas can improve the system performance.

Key words: Ad hoc networks, directional antennas, MAC protocols
