Advanced Macro Mobility Handover Supporting Fast Handover in HMIPv6

摘要

In proportion to the increase of a number of various wireless devices and development of wireless access technologies, mobile users desire to access the Internet regardless of their location at anytime. In Hierarchical Mobile IPv6 (HMIPv6) when a mobile node (MN) moves from a MAP domain to another, it can experience disruption of connection as well as packet loss due to a long handover latency. To cope with these problems, we propose an advanced macro mobility scheme to reduce handover latency and packet loss. We adopt the fast handover scheme from FMIPv6 to optimize the performance of the proposed scheme. In this paper, we analyze the handover latency for various protocols and compare to our scheme with analytical model. The results show that the proposed scheme is better approach to handle the mobile node's movement than the other protocols.
