Abstract
In this paper, we propose cost-reduced binding update scheme (CRBU) which further reduces signaling traffic for location updates by employing virtual mobility anchor point (VMAP) on top of overlapped MAP in Hierarchical Mobile IPv6 (HMIPv6). This proposed scheme significantly improves performance compared to HMIPv6, in terms of binding update rate per user and average handoff latency. Also it makes the mobile nodes (MNs) moving around the boundary access routers (ARs) of adjacent MAPs and they become to move within a VMAP. It is certain that our scheme uses the network resources efficiently by the removal of global binding updates for MNs in boundary ARs inside MAPs. And we explain an analytic model for performance analysis of HMIPv6 networks, which is based on the random walk mobility model. Based on this analytic model, we formulate binding update cost and analyze it as the probability that an MN stays in the current cell (q). As a result, our proposed scheme can greatly reduce the packet loss and delay by eliminating Inter-MAP handoff.
