An efficient micromobility implementation for 802.1X WLANs

We analyze the implications of the integration of the current IP micromobility concepts with the 802.1X access control. We show that the independent user location tracking of IP micromobility and 802.1X provokes a significant additional handover delay and signaling load degrading the overall performance. To overcome these difficulties, we propose a system architecture which uses EAP as a general signaling protocol. We then discuss the new opportunities of our approach. Finally, we show that our system architecture can be applied in almost all access networks by exploiting the generality of the 802.1X approach.
