摘要: 传统无线区域网路架构已经被广泛的使用多年,其主要是由多功能的智慧型撷取点及第二层的网路协定交换器所构成,藉以此建构出无线区域网路的骨干架构。然而,这种架构存在着许多的缺点,包含较高的网路管理及网路建构成本,整体性的效能低落等等。假若此传统无线区域网路架构和IEEE 802.1x整合使用,一旦使用者在不同的撷取点之间快速的移动,那么换手延迟的时间将无法满足一些即时性的多媒体应用程式的需求。因此在本篇论文中,我们将建构一个以及轻量化撷取点为基础,且为集中式管理的无线区域网路架构来改进传架构上的缺失。另外,本文也会提出一个改良式的IEEE 802.1x 认证程序来减少换手的延迟,而实验证实我们的方法比原有的方法要好。
Traditional WLAN architecture has been used for several years. It consists of intelligent access point and layer 2 switch and uses as a WLAN backbone infrastructure. However, it has many drawbacks such as high overhead of network management, high construction cost and low performance. Once traditional WLAN architecture works together with the IEEE 802.1x mechanism and the mobile host moves between different access points quickly, the handoff delay will not meet the requirement of real-time multimedia application. In this thesis, we will construct a centralized WLAN architecture based on the Thin AP architecture to improve the weak points of the traditional WLAN architecture. A modified IEEE 802.1x authentication procedure is also presented to decrease the handoff delay, and the experiment shows that the novel mechanism is better than the original one.
