Location management using mobile history for hierarchical mobile IPv6 networks

Hierarchical mobile IPv6 (HMIPv6) has been proposed to improve the performance capability of mobile IPv6 at handover. In HMIPv6, local entities named mobility anchor points (MAPs) are distributed throughout a network to localize the management of intra-domain mobility. In this paper, we propose a location management method for hierarchical mobile IPv6 using the mobile node´s (MN) mobile history. In this method, when a MN performs a handover, the access router calculates the area-covered rate of each upper MAP from the MN´s mobile history and selects the MAP that best manages the MN in accordance with its rate. Thus, the proposed method reduces both the number of binding updates to the home agent and the signaling traffic. We evaluate the performance of the proposed method by simulation.
