This paper proposes a new mechanism of setting up QoS connection –
RSVP and 802.16 operating integrated procedure, it can work in the IEEE
802.16 and IEEE 802.11e hybrid network, and how to transfer QoS link from
the serving SS to target SS when the mobile node moved from serving SS to
the target SS. Furthermore, we propose a mechanism of dynamic bandwidth
management, it make the real-time services get high priority to acquire
bandwidth when the real-time services do the handoff procedure and reduce
handoff call blocking probability when the resource is insufficient.
Simulation results show the mechanism of dynamic bandwidth
management can meet the handoff call blocking probability is reduced when
the real-time services do the handoff procedure if the parameters are configured
appropriately.
