Abstract

The integration of IEEE 802.11 wireless LAN andMobile IP technologies offers an affordable and highbandwidth solution for host mobility. When applying theHierarchical Mobile IP for Fast Handover, theperformance bottleneck on Mobile IP and potentialdisconnection during handoff period can be greatlyimproved. However, the Fast Handover protocol suffersseveral problems such as scalability and QoS support forlacking a buffer management mechanism. In this work, wepropose an enhanced buffer management scheme for Fasthandover. By means of the proposed scheme, we are ableto improve the buffer utilization on routers as well as tosupport QoS services during a handoff process. Using thens-2 simulator, we have demonstrated the significanceand effectiveness of our proposed scheme.
