A Pointer Forwarding Scheme With Mobility-Aware Binding Update in Hierarchical Mobile IPv6 Networks

In this paper, the authors propose a pointer forwarding scheme with mobility-aware binding update in Hierarchical Mobile IPv6 networks. In the proposed scheme, a pointer chain between Access Routers (ARs) is established to reduce the Binding Update (BU) traffic to the Mobility Anchor Point (MAP). In addition, the MN performs a binding update to the Correspondent Node (CN) depending on its mobility. Specifically, an on-Link Care-of Address (LCoA) is chosen for the MN with low mobility whereas a Regional Care-of-Address (RCoA) is selected for the MN with high mobility. This mobility-aware binding update can reduce the packet delivery overhead in an adaptive manner.
