Abstract

Hierarchical Mobile IPv6 (HMIPv6) guarantees to reduce handoff latency, because the MN only registers the new addresses at mobility anchor point (MAP) when the MN moves around access routers (ARs) in the same MAP domain. HMIPv6 still has packet loss problem when the MN moves from one MAP to another. In this paper, a novel location update scheme which further reduces signaling traffic for location update by employing virtual MAP (VMAP) on top of overlapped MAP in HMIPv6, is proposed. This proposed scheme significantly improves performance compared to HMIPv6, in terms of location update rate per user. Also it makes the mobile nodes (MNs) moving around the boundary ARs of adjacent MAP’s become to move within a VMAP. It is certain that this scheme reduce the network resources efficiently by reason of removing the location update. In conclusion, this scheme greatly reduces the packet loss and delay, due to Inter-MAP handoff not occurring.
