3S: Scalable, secure and seamless inter-domain mobility management scheme in proxy mobile IPv6 networks

PMIPv6 has received considerable attention between telecommunications and the Internet communities and does not require active participation of the Mobile Node (MN) by way of network-based mobility management. In this paper, we are proposing a novel 3S scheme for building Scalable, Secure, and Seamless PMIPv6 domains. In the proposed scheme, all of the Mobility Access Gateways (MAGs) are acting as the Local Mobility Anchor (LMA) combining a virtual ring with another MAG. General hashing is used in the efficient distribution-mapping between each MN and the MN's LMA for all MAGs. Also, the MAG and the MN are authenticated using the symmetric key. Through mathematical analysis, we verify the safety, scalability, and seamless service for 3S. Furthermore, we propose a handover procedure of 3S, which demonstrates its superiority over the existing schemes in terms of handover latency.
