Abstract
With the popularity of portable devices, public Internet access service using wireless LAN has started in many countries. In the public wireless LAN network, since re-authentication latency during handoff affects the service quality of multimedia applications, minimizing authentication latency is very important in order to support real-time multimedia applications on the wireless IP network. In this paper, we proposed a fast handoff scheme using the predictive authentication method based on IEEE 802.1x model. In our scheme, a mobile host entering an area of an access point (AP) performs authentication procedures for a set of multiple APs instead of the current AP. Multiple APs are selected using a Frequent Handoff Region (FHR) selection algorithm considering users? mobility patterns and their service classes. Since a mobile host is authenticated for FHR in advance, the handoff latency due to the re-authentication can be minimized. Simulation results show that the proposed scheme is more efficient than other schemes in terms of delay.
