WLAN无漫游组网方式设计与实现

针对无线局域网传统"微蜂窝架构"组网方式下终端漫游时存在的时延增大、丢包和断流等问题,提出了一种软件定义的WLAN无漫游组网方法,通过将多个AP(AccessPoint,无线接入点)虚拟成一个"大虚拟AP"的方式,使终端始终关联在该"大虚拟AP"上,从而使得终端可在AP间无漫游地切换并维持数据通信的连续性。实验结果表明,该方法使终端在切换AP时比传统"微蜂窝架构"组网方式下的漫游具有更快的文件传输速度和更好的稳定性,增强了网络实时性。

DESIGN AND IMPLEMENTATION OF A ROAM FREE NETWORKING METHOD FOR WLAN

In this paper, a software-defined WLAN roaming-free networking method is proposed to address the problems of delay increase, packet loss, and flow interruption that may exist during terminal roaming in the traditional microcellular architecture networking mode of wireless local area networks. The manner in which multiple APs are virtualized into a big virtual AP enables the terminal to always be associated with the big virtual AP, so that the terminal can switch between APs without roaming and maintain the continuity of data communication. The experimental results show that this method enables the terminal to have faster file transmission speed and better stability whenswitching the AP and roaming under the traditional micro-cellular architecturenetworking mode, which enhances the network real-time performance.
