Dynamic load control mechanism in hierarchical MIPv6

Hierarchical Mobile IPv6 (HMIPv6) introduced by IETF to enhance mobility problem in the next generation Internet Protocol (IPv6). The key concept behind HMIPv6 is the usage of Mobility Anchor Point (MAP) located at any level in a hierarchical network to support micro-mobility management and seamless handover. Therefore the furthest MAP selection in HMIPv6 can be a MAP overload and increases frequent Binding Update problem as the network extends. The major issue on HMIPv6 is to design the MAP selection scheme that can reduce MAP load without affecting the network performance. To solve this issue, we proposed and discussed a dynamic load control mechanism that combines with the distance MAP selection scheme. From the experimental results we obtain that the proposed scheme gives better distribution in MAP load and improves handover speed.
