Abstract

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
