Fast Mobile IPV6 handoff using cross layer interaction

摘要

FMIPv6 always fails to perform predictive handoff procedure and results in reactive handoff when integrated with the IEEE 802.11-based standard. It is because of the protocol nature of IEEE 802.11 and the weak relationship between IEEE 802.11 and FMIPv6. Furthermore, a Mobile Node (MN) can not receive packets destined to it as it sends the Fast Binding Update (FBU) to the old Access Router (oAR). This would cause unnecessary packet loss and make the predictive handoff have more packet loss then reactive. In this paper, FMIPv6 scheme will be proposed, which is based on an interaction between L3 and L2. It can reduce the unnecessary packet loss when the handoff occurs and avoid the longest phase that IEEE 802.11 will enter, and can lower the handoff latency.
