Next-Generation Wireless Networks (NGWNs) present an all-IP-based architecture integrating
existing cellular networks with Wireless Local Area Networks (WLANs), Wireless Metropolitan Area
Networks (WMANs), ad hoc networks, Bluetooth, etc. This makes mobility management an
important issue for users roaming among these networks/systems. On one hand, intelligent
schemes need to be devised to empower mobile users to benefit from the IP-based technology. On
the other hand, new solutions are required to take into account global roaming among various radio
access technologies and support of real-time multimedia services. This paper presents a
comprehensive performance analysis of Fast handover for Hierarchical Mobile IPv6 (F-HMIPv6)
using the fluid-flow and randomwalk mobility models. Location update cost, packet delivery cost and
total cost functions are formulated based on the proposed analytical models. We investigate the
impact of several wireless system factors such as user velocity, user density, mobility domain size,
session-to-mobility ratio on these costs, and present some numerical results.
