Hierarchical mobile IPv6 (HMIPv6) has long been prevailing in the realm of effective micromobility management. The HMIPv6 protocol, associated with mobile IPv6, supports route optimization to resolve 'triangle-routing' problem, and enables local route registration within a MAP domain to reduce the amount of network-wide signaling traffic. But most of the researches on micromobility related protocol were focused on access networks with tree topology, which have severely limited flexibility and scalability of access networks. In this paper, a novel local route optimization scheme is proposed to facilitate applying HMIPv6 to access networks with various topologies. By dynamically optimizing route to the mobile anchor point according to access network topologies, the new scheme could significantly reduce signaling overhead, handoff latency and packet loss.
