摘要
介绍了无线Ad-hoc网络MAC层协议面临的问题,重点分析了隐蔽终端问题和暴露终端问题产生的原因以及解决这些问题相应的策略。在此基础上提出了一种结合了定向天线、RTS/CTS握手和信道分割的新的MAC协议。
This paper introduces the challenge of medium access control (MAC) for the wireless Ad- hoc networks, analyzes the causation of hidden terminal and exposed terminal, and gives some suggestions for such problem. In addition, it presents a new protocol combined with directional antenna, RTS/CrS, and distributed channel.
