摘要
随着无线技术的快速发展,越来越多的用户希望能够在任何时间、任何地点均能实现数据通信的目标,因此,实现移动用户在不同无线接入点AP(access point)间自动切换是一个大的趋势。主要研究和实现无线局域网中客户端在不同AP间自动切换功能,以软件实现的方式在Linux操作系统平台上实现自动切换。仿真结果表明客户端能够检测到通信端范围内所有AP,并自动判断选择接入的AP进行连接,实现Internet的接入,以及对所需的切换时间进行了分析与讨论。
With the rapid development of wireless able to achieve the goal of data communications at technology, more and more users long to be any time and at any place. Therefore, it will be a big trend that mobile users can automatically switch at different APs （access points）. This paper studied and realized automatic switching of WLAN clients among different APs by means of software on the Linux platform. Simulation results show that clients can detect all the APs within the communications terminal and automatically determine and choose the AP to achieve Internet access. In addition, the switching time was analyzed and discussed.
