N2 - The host-based protocols, Mobile IPv6 protocol (MIPv6), Hierarchical Mobile IPv6 (HMIPv6), and Fast Mobile IPv6 (FMIPv6), require that the mobile terminals include the mobility functions. To address this issue, Proxy MIPv6 (PMIPv6), a network-based protocol, has recently emerged. Despite its advantage of easier practical application, PMIPv6 still has some weak points, disconnection and transmission delay, during handover. This paper, therefore, proposes a scheme that reduces handover latency by simplifying the user authentication procedure required when a mobile node (MN) enters a new wireless network domain. And it also saves transmission cost by storing packets in the optical buffering module of the local mobility anchor (LMA) and retransmitting those packets after handover phase. Performance evaluation conducted using an analysis model indicates that the proposed scheme shows a performance improvement of 33% over standard PMIPv6 in terms of handover latency, and 67% over Seamless handover scheme in terms of the transmission cost due to the retransmission of buffered packets.
