Abstract

Proxy Mobile IPv6 (PMIPv6), a network-based localized mobility protocol, allows a mobile node (MN) to move around within the same PMIPv6 domain by keeping the same IP address. However, PMIPv6 does not support the global handover since it supports only an intra-domain handover. To support the global handover, MNs need to load the protocol stack for the global mobility. Our proposed scheme enables the MN’s session to be connected without any support of PMIPv6 protocol during the global handover. In addition, it reduces the packet transmission delay by performing the Route Optimization (RO) after the MN’s global handover. In this paper, we compare our proposed scheme with the existing Roaming scheme. As a result, the proposed scheme reduces the packet transmission delay by 25% and the packet loss by 78% compared with the existing one. In other words, our scheme supports the seamless and reliable handover for MN.
