—As technologies for the high quality multimedia
application and 4G WiMAX network prevail, one can easily be
under services everywhere through WiMAX wireless network.
However, the service disruption time (SDT) caused by handover
procedure leads to an unacceptable quality of service (QoS) for
mobile users, especially in IEEE 802.16j mobile relay station
(MRS) mode. Therefore, we proposed a host-based fast mobility
scheme (HFMS) in IEEE 802.16j MRS mode to reduce the SDT
and solve the packet loss problem during handover via the
cooperation between the MRS's link-layer and mobile station's
(MS's) IP layer. In the proposed scheme, the MRS's link-layer
will notify the MS's IP layer to perform IP layer handover
procedure when the MRS performs link-layer handover. The
parallel handover reduces the SDT efficiently. On the other
hand, the proposed buffering mechanism can avoid packet loss.
As a result, the seamless mobility and satisfactory QoE can be
achieved for mobile users in IEEE 802.16j MRS mode.
