FH-RSVP scheme for intra-site handover in hierarchical mobile IPv6 networks

This paper proposes a new RSVP and Mobile IP interworking scheme, called FH-RSVP, to support QoS of real-time applications in mobile environments. FH-RSVP uses unicast sender-oriented RSVPs with HMIPv6 protocol and makes anticipated reactive resource reservations based on fast handover principles when an intra-site handoff can happen to WLAN access radio medium. Simulation results show that our proposal achieves better QoS guarantees than MRSVP in terms of setup time for the resource reservation path, throughput and packet losses. Furthermore, FH-RSVP is more efficient than MRSVP in terms of reservation blocking, forced termination and session completion probabilities.
