3.INTRODUCTION
WiMAX is an acronym of Worldwide Interoperability for Microwave Access.
It is an IP based, wireless broadband access technology.
It is used in Metropolitan Area Networks.
It supports both fixed and mobile applications.
It is used in both 3G and also 4G technology.
4.RELATED WORK
5.OBJECTIVE
Main motive of the mobile technologies is to provide seamless cost effective mobility.
But this is affected by Authentication cost and handover delay.
Proposed Pre-Authentication method is intended to reduce the authentication delay by getting pre-authentication Certificate(PAC) by central authority called Pre Authentication Authority (PAA).
MS having time bound PAC can skip the authentication process when recognized by target BS during handoff.
6.HANDOVER PROCESS
7.Handover process normally has 9 steps. From this 9 steps, 4steps is utilized for authentication. So it has more time during this process.
Authentication is the initial step of the Handover Process. It enhances the delay during handover. It can be reduced by using Pre-authentication process.
8.TERMINOLOGIES
9.Pre-Authentication Before Handover
10.Pre-Authentication is performed before the Handover process.
First PAA (Pre Authentication Authority) verifies the identity of MS.
If verification succeeds means, PAC(Pre-Authentication Certificate) and CET (Certificate Expiry Time) is distributed from PAA to MS and also to the Neighboring BSs (Base Stations).
After PAC distribution, The Handover process begins between MS and BS.
