In wireless network data link layer is built on the physical layer , and it consists of two part : mac layer and llc ( logic link control ) layer 在此基础上进行了无线收发电路的设计和调试。数据链路层建立在无线通道之上,包括mac层和llc层。
This paper first analyzed basic functions ? rror control and flow control which are mainly completed in logic link control layer , then discussed several mac protocols which are often used in wireless network 本文首先介绍了llc层要完成的基本功能? ?差错控制和流量控制,讨论了无线网络中常用的mac协议,然后介绍了本系统采用的mac协议的控制过程。
