Network independent mobility management scheme using virtual IP addressing

Recent innovation in mobile technologies has changed from the static architecture of client-server relationships toward dynamic, mobile, and instant networks. Accordingly, many studies have been done to support the seamless mobility networks. However it is difficult to deploy such networks due to the need of a special network infrastructure supporting mobility management. In this paper, we propose a novel mobility management scheme without depending on any essential network infrastructure. It establishes a direct tunnel between a Mobile Node (MN) and a Correspondent Node (CN) using virtual IP addressing. The assigned virtual IP addresses of MN and CN are fixed during their communication session via the tunnel. When MN is moving, the changes of its physical IP address are updated to CN by the Virtual Tunnels (VTUN) layer to keep their communication session. The performance evaluation results show that the proposed scheme significantly reduces the L3 handover latency compared with that of PMIPv6.
