Paper Abstract

The current generation of wireless networks has been designed predominantly to support voice and more recently data traffic. WiMAX is currently one of the hottest technologies in wireless. The main motive of the mobile technologies is to provide seamless cost effective mobility. But this is affected by Authentication cost and handover delay since on each handoff the Mobile Station (MS) has to undergo all steps of authentication. Pre-Authentication is used to reduce the handover delay and increase the speed of the Intra-ASN Handover. Proposed Pre-Authentication method is intended to reduce the authentication delay by getting pre authenticated by central authority called Pre Authentication Authority (PAA). MS requests PAA for Pre Authentication Certificate (PAC) before performing handoff. PAA verifies the identity of MS and provides PAC to MS and also to the neighboring target Base Stations (tBSs). MS having time bound PAC can skip the authentication process when recognized by target BS during handoff. It also prevents the DOS (Denial Of Service) attack and Replay attack. It has no wastage of unnecessary key exchange of the resources. The proposed work is simulated by NS2 model and by MATLAB.
