Fast handover protocol provides seamless handover in mobile IPv6 networks by reducing handover latency. One assumption in fast handover is that the MN (Mobile Node) or the network could know or predict the new AR (Access Router) before data transport from the previous AR to the MN is disrupted. In order to achieve this capability, the complexity of predicting the new AR and the diversity of the wireless...
