The Future Enhancements of Mobile Ipv6 Micro-Mobility Management

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 its “home address”. Hierarchical Mobile IPv6 (HMIPv6) was designed to enhance mobility support in MIPv6 and micro-mobility management. 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. The major issue on HMIPv6 is designing the MAP selection scheme that can reduce frequent Binding Update process and improve handover performance. This paper discussed and reviewed the enhancements of MIPv6 in term of Local Binding Update, MAP Discovery and MAP selection scheme.
