对无线客户端与无线接入点连接机制的研究

Research on the connectionism of wireless client and wireless access point

基础结构WLAN中,无线客户端通过无线接入点转发数据之前,必须首先建立它们之间的无线连接。研究基础结构中的无线客户端与无线接入点连接的机制,介绍了IEEE 802.11协议帧结构,提出了建立无线连接的Scanning(扫描)、Joining(加入)、Authentication(认证)与Association(关联)四个进程,分析了无线客户端与无线接入点的握手过程。

In infrastructure WLAN, before wireless client transmitting data through wireless access point, the wireless connection should be established between them. This paper studies the connectionism, introduces the frame structure of IEEE 802.11 protocol, puts forward the four processing in the building of wireless connection： scanning, joining, authentication and association, and analyzes the handshake process of wireless client and wireless access point.
