FH-PMIPv6: A fast handoff scheme in Proxy Mobile IPv6 networks

Mobile IPv6 (MIPv6) is a host-based mobility management protocol that provides continuous service for mobile nodes (MNs) when they change their attachment points. However, MIPv6 is not suitable for real-time services because it causes long disruptions during handoff. Recently, the IETF NETLMM working group proposed a network-based localized mobility management protocol, called Proxy Mobile IPv6 (PMIPv6) to support mobility management without the participation of MNs in any mobility-related signaling. Unfortunately, PMIPv6 still suffers from the packet loss problem and long authentication latency during handoff. Therefore, we propose a fast handoff scheme in PMIPv6 networks called FH-PMIPv6, to provide low handoff latency, resolve the packet loss problem, and reduce signaling cost. Moreover, we evaluate FH-PMIPv6 via analytical model, and the results show that the FH-PMIPv6 provides a better solution than existing schemes.
