Semi-soft FMIPv6 for 802.11 Network
Mobility support in the wireless network enables us to be served continuous service. Fast Handover for Mobile IPv6 (FMIPv6) is proposed to support a faster handover than that of Mobile IPv6. Unfortunately, FMIPv6 shows too long handover latency to serve smooth video traffic flows. We proposed semi-soft FMIPv6 handover to minimize the handover latency to serve video traffic efficiently. The proposed scheme clarifies the handover procedure by separating the handover preparation and the actual handover. We also clarify the use of L2 triggering by introducing four triggers and triggering time scheme. With our experimental implementation, the proposed scheme has shortened the handover latency below 50ms and this low handover latency helps to reduce the buffered packet size in access routers.
