Abstract

Mobility management and QoS provisioning are both key techniques in the future wireless mobile networks. In this paper we propose a framework for supporting QoS under an enhanced “Fast Handovers for Mobile IPv6” (FMIPv6) architecture. By introducing the key entity called “Crossover Router” (CR), we shorten the length of packet forwarding path before the MN completes binding update. For QoS guarantee, we extend the FBU and HI messages to inform the NAR of the MN's QoS requirement and make advance resource reservation along the possible future-forwarding path before the MN attaches to the NAR's link. We keep RSVP states in the intermediate routers along overlapped path unchanged to reduce reservation hops and signaling delays. The Performance analysis shows that the proposed scheme for QoS guarantee has lower signaling cost and latency of reservation re-establishment, as well as less bandwidth requirements in comparison with MRSVP.
