A Predictive Binding Mechanism on Multi-Interface MN in PMIPv6

Because of a MN´s multi-interface sharing a unique network prefix, more resource shall be consumed owing to multiple copies of every packet being forwarded to a Mobile Node (MN) in a Proxy Mobile IPv6 (PMIPv6) domain. It may also result in network congestion and some security issues. To tackle the issues, a predictive binding mechanism is presented in this paper. It enables a Local Mobility Anchor (LMA) know the IP addresses of all or some interfaces belonging to a MN. The mechanism reuses and extended the existing register message to convey the learned IP address. Minimum extension of messages is defined and detailed message sequence charts are elaborated for the presented mechanism. Moreover, its technical features and performance analysis are provided. It does not change the BCE´s matching principle of PMIPv6 and abides by the network prefix match. The mechanism can also suite the alternation of IP address and any possible radio access technologies and provide well expansibility.
