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-to-end 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.
