In a network-based approach such as proxy mobile IPv6 (PMIPv6), the serving network
controls mobility management on behalf of the mobile node (MN). Thus, the MN is not
required to participate in any mobility-related signaling. PMIPv6 is being standardized in the
IETF NetLMM WG. However, the PMIPv6 still suffers from a lengthy handover latency and
packet loss during a handover. In this paper, we propose a seamless handover scheme for
PMIPv6. The proposed handover scheme uses the Neighbor Discovery message of IPv6 to …

PMIPv6 is proposed as a new network-based mobility protocol and it does not require MN's
involving in mobility signaling. PMIPv6 can handover relatively faster than MIPv6 because of
using link layer attachment information and micro mobility characteristic. However, current
PMIPv6 cannot prevent packet loss in disruption period. We proposed in this paper, Smart
Buffering scheme for supporting seamless handover in PMIPv6. Smart Buffering scheme
prevents packet loss totally by buffering lost candidate packets in a current serving MAG and …
