An extension to mobile IPv6 micro-mobility management

A Mobile IPv6 (MIPv6) supports mobility and takes advantage of the new design in IPv6 by allowing a mobile node move to another location without changing the mobile node´s “home address”. A Hierarchical Mobile IPv6 (HMIPv6) was designed to enhanced mobility problem in MIPv6. The key concept behind HMIPv6 is to locally handle handovers by the usage of an entity called Mobility Anchor Point (MAP) located at any level in a hierarchical network of routers to support micro-mobility management. The major issue on HMIPv6 is to design the MAP selection scheme that can reduce frequent Binding Update process and improve handover performance. This paper discussed and reviewed the extension of HMIPv6 in term of Local Binding Update, MAP Discovery and MAP selection scheme.
