Evaluation of EAP based Re-authentication Protocol for High-speedVehicular Handover in Cognitive Radio Networks

The future wireless network technologies, such as a cognitive radio (CR) network, will be able to change their configuration in the communication environment automatically. However, the authentication frameworks for various radio technologies are quite different from one another. In order to support radio reconfiguration, we proposed a radio-independent mutual authentication protocol (EAP-CRP) and a re-authentication protocol (EAP-CRP re-authentication) for CRs. This paper describes the evaluation of the EAP-CRP re-authentication for high-speed handover. The handover process has to be accomplished during the period that the mobile node stays in an overlapped area covered by ranges of the both access points. We resolved the probability of the success of the re-authentication process by making a handover simulation model, then, we estimated the model on a network simulator. As a conclusion, this paper shows that the EAP-CRP re-authentication contributes to the successful of the handover rather than any other AAA server-based authentication method even if the mobile node moves with high-speed.
