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.</span></span><span style="font-family: ";Arial";,";sans-serif";; font-size: 8.5pt;"></span></p

Performance Analysis of Seamless Handover in Mobile IPv6-based Cellular Networks

“…The main idea of SMIPv6 (Zhang et al, 2005;Zhang & Marchand, 2009;Zhang & Pierre, 2008;) is to pre-configure bidirectional secure tunnels among access routers before actual handover and to utilize such tunnels to accelerate mobility management procedure of FMIPv6 (Koodli, 2008). The quality of service related parameters (e.g.…”

“…Additionally, neither signaling overheads nor packet losses are effectively reduced using FMIPv6, thus supporting seamless mobility becomes impossible. F-HMIPv6 allows mobile users to benefit from both FMIPv6 and HMIPv6, but the handoff latency for intra-domain roaming lasts about 90ms whereas the handover delay for inter-domain roaming rises to about 240ms (Jung et al, 2005), making this protocol unsuitable for multimedia streaming traffic (Zhang & Pierre, 2008). As a result, none of these protocols provides a perfect solution for seamless mobility management.…”

“…As a result, none of these protocols provides a perfect solution for seamless mobility management. Under the circumstance, we propose a new protocol called seamless mobile IPv6 (SMIPv6) (Zhang et al, 2005;Zhang & Marchand, 2009;Zhang & Pierre, 2008;). Compared with current alternatives, the key advantage of our proposal is that (1) mobile nodes don't have to be equipped with multiple radio interfaces; (2) forwarding IP packets from the PAR to NAR is carried out much earlier than FMIPv6 and F-HMIPv6; (3) Ongoing real-time session is resumed on the new link much earlier than FMIPv6 and F-HMIPv6; (4) it is flexible to work with MIPv6 and HMIPv6; (5) SMIPv6 can support multimedia streaming traffic during handoff.…”

QoS Improvement for the Next Generation Heterogeneous Network

“…FMIPv6 is designed to enable the MN to rapidly detect its movements and to obtain a prospective IP address with a new AR while being connected to a current AR [9].…”

“…In this paper a novel hybrid coupled interworking model that integrates Worldwide Microwave Access network (WiMAX), a Wireless Local Area Network (WLAN) and a Long Term Evolution network (LTE) is proposed with IPQoS and LB [8]. Heterogeneous network model based on Fast handover Hierarchical Mobile IPV6 (FHMIPV6) [9] protocol that integrates the WiMAX, LTE and WLAN technologies is proposed to improve QoS. The QoS parameter in terms multimedia application such as traffic sent and received, RTP, response time, jitter, packet end -to-end delay, packet delay variation, is simulated and its performance were measured.…”
