摘要：

实现WiFi、WiMAX异构无线网络间的快速互联互通,需保证用户设备在无线网络切换时有较小的时延,同时又要保证切换时的通信质量。针对WiFi-WiMAX组网环境中切换认证时需要重复进行EAP认证,从而导致过高切换延迟的问题,文章提出一种快速认证机制,在用户设备初次入网执行完全EAP认证后,保留切换网络时所需要的MSK,并把MSK提前送至目标网络,网络切换时直接采用再利用密钥的方法进行认证,以达到快速认证的目的。文章通过NS2对提出的快速认证机制进行了模拟实验与分析,实验结果证明快速切换方法获得了最短的平均切换时延,改进了网络的认证效率,为用户提供了更好的QoS。

Abstract:

To achieve fast interconnection between WiFi and WiMAX heterogeneous wireless network, it needs to make sure the user facility has small delay when switching in the wireless network, and it also needs to guarantee the communication quality when switching. In the WiFi-WiMAX heterogeneous wireless network, the authentication method requires the user to repeat full EAP authentication, which leads to excessive delay and influences the transmission quality. This paper puts forward a fast authentication mechanism that after completing the EAP authentication when users’ equipments access network for the first time, the MSK that is needed when switching network is kept and sent to the target network in advance. This paper adopts the method of reusing the key to achieve the goal of rapid authentication when switching network. Experiment is set with NS2 to prove that fast switching method obtains the shortest average switching delay, improving the efficiency of network authentication, and providing better QoS for the users.

Key words: heterogeneous network, fast switching, WiFi-WiMAX
