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 在此基礎上進行了無線收發電路的設計和調試。數據鏈路層建立在無線通道之上,包括mac層和llc層。
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 本文首先介紹了llc層要完成的基本功能? ?差錯控制和流量控制,討論了無線網絡中常用的mac協議,然后介紹了本系統采用的mac協議的控制過程。
