Abstract
The Internet Engineering Task Force (IETF) has standardized Proxy Mobile IPv6 (PMIPv6). Fast Handovers for Proxy Mobile IPv6 (PFMIPv6) was studied by mipshop working group to reduce packet loss in PMIPv6. PFMIPv6 is fast handover extension of PMIPv6. PFMIPv6 handover latency is longer than PMIPv6, although it reduces packet loss in PMIPv6. In this paper, we propose Enhanced PFMIPv6 to reduce handover latency. In the proposed scheme, the Proxy Binding Update (PBU) message is sent to Local Mobility Agent, in advance, when new mobile access gateway (NMAG) receives the Handover Initiate (HI) message. The HI message includes necessary information to build PBU. We analyze the performance of EPFMIPv6 compared with PMIPv6 and PFMIPv6 mathematically.
