Though some studies involving general micro-mobility exist, micro-mobility research concerning a mobile node (MN) moving between Mobile Anchor Points (MAP) is lacking. In Hierarchical Mobile IPv6 (HMIPv6), a MN sends a binding update (BU) message to a MAP when the MN performs a handoff. This scheme reduces the handoffs and BUs performance costs. However, the total signaling cost of HMIPv6 rapidly increases with the number of corresponding nodes (CN) for a MN moving among MAPs. In this paper, we propose a scheme based on logical topology with autonomous configuration allowing a MN to move around between MAPs without performing a BU. We perform the performance evaluation for packet delivery and location update costs through a novel analytic approach. We show that the proposed scheme is approximately two times better than the existing one in terms of the total signaling costs through performance analysis. Furthermore, our scheme also reduces the location management cost effectively.
