Abstract:


The mobile Virtual Private Network (MVPN) of the Internet Engineering Task Force (IETF) is not designed to support NEtwork MObility (NEMO) and is not suitable for real-time applications. Therefore, architecture and protocols to support VPN in NEMO are needed. In this paper, we propose a cost-effective and secure mobility management scheme (SeSIP) that is based on session initiation protocol (SIP) and designed for real-time applications with VPN. Our scheme to support MVPN in NEMO enables the session to be well maintained during movement of the entire network. Further, in order to reduce the authentication delay time in handoff operations, the signaling time which occurs to maintain the session is shortened through our proposed handoff scheme which adopts authentication using HMAC-based one-time password (HOTP). Our performance analysis results show our proposed scheme provides improvement in average handoff performance time relative to existing schemes.
