“…Also, It has been proved in [8] that using two-level MAPs in the HMIPV6 can reduce the transmission distance of the signalling messages as well as their number. By considering these two findings as our assumptions, we place the first MAP on the gateway node(GMAP Inter-LMAP HandOver: When the MN enters a domain belonging to a new LMAP, the new LMAP is in charge of updating the current location with the GMAP.…”

This paper presents a new way of using an aggregated RSVP tunnel mechanism in nested HMIPv6 in order to improve QoS for the Mobile Node (MN). This technique consists of two-layer Mobility Anchor Points (MAPs) named Global MAP(GMAP) and Local MAP(LMAP). The first MAP (GMAP) is placed at the gateway to the Internet and the other MAPs (LMAPs) are placed between the GMAP and MNs. There are pre-configured RSVP tunnels between the GMAP and each of the LMAPs. These RSVP tunnels are in charge of aggregating and providing the RSVP requested resources for all the MNs belonging to the same LMAP domain. The proposed mechanism is intended to provide better QoS for MNs by expediting the end-to-end RSVP re-establishment process between the MN and Correspondent Node (CN) during the intra-domain handover. Moreover, by using the new extension for the conventional RSVP tunnel, the proposed scheme reduces the number of the end-toend RSVP signalling messages passing through the RSVP tunnel. An appealing feature of the proposed scheme is that it needs minimum changes in the LMAP and GMAP nodes for RSVP tunnel establishment and optimization, without affecting any of the conventional RSVP routes in between. The paper evaluates the performance of the proposed solution compared to the well known RSVP-MP (Mobile Proxy) by means of the simulation experiments modelled in the Network Simulator version 2 (NS-2). The results indicate an average of 95% improvement for the resource reservation latency, an average of 93% reduction in the number of packets treated as a best-effort after completion of handover (inter-LMAP and intra-LMAP handover) and up to 34% less packet dropping during the intra-LMAP domain handover. The results indicate the superiority of the proposed scheme to RSVP-MP.

“…For this purpose, Virtual Mobile Anchor Point (VMAP) nodes were added under the HMIPV6 network environment to shorten the distance of the MNs (Mobile Nodes) signal transmission and to reduce the number of signals. However, the problem of long delays persisted, and the problems were further burdened by the loss of transmission packets [1], due to the time consuming process of Binding Update (BU) [2]. This paper proposes a new scheme to improve the long Local Binding Update (LBU) procedure and reduce the effect that was caused by Handover delays.…”

“…While HMIPv6 introduces the additional delay for establishing the bidirectional tunnel between MAP and MN, generates the more signal load for Inter-MAP handover. Furthermore, it is difficult to determine an adaptive MAP domain size for different MN's mobility pattern [6] [7].…”

Abstract. Mobile IPv6 permits the Mobile Node (MN) to maintain the continuous connectivity to the Internet when it moves from one access router to another. Due to both link switching delay and IPv6 protocol operation during the handover process, packets destined to the MN can be delayed or lost. This paper proposes a solution to improve the Mobile IPv6 handover performance over wireless network by introducing a new entity -Extension Handover Control Function (E-HCF). E-HCF could send the decisive control message to MN to accelerate the handover process and manage the traffic belonging to MN to reduce the packet loss. With a comparison between Mobile IPv6 and our E-HCF solution, we show that our solution allows us providing low-latency and low packet loss for real-time services during the handover.
