Abstract: In this paper, we introduce a technique to reduce the authentication overhead for handoff process in wireless local area networks (WLAN). It is based on user mobility prediction to reduce the network scanning area during the handoff procedure. The central server facilitates an intelligent mobility prediction mechanism to identify the next possible mobile access points for mobile subscriber. The predicted information is managed by an event log table, and it helps to reduce the authorisation overheads for cellular networks. It follows the reserve channel scheme to maintain the QoS for users during the call and handoff procedure and the handover-call has higher priority over local initiated call. The analytical model shows the effectiveness and efficiency of proposed work, we apply the Markov random walk model and M/M/1 queuing model to formulate our work. It is compared with the tradition technique, and has 40% better result than legacy techniques.

Keywords: wireless access point; handoff management; pre-authentication; mobility prediction; network overheads.
