Abstract
In the fast handover scheme, MN can prepare for handover when the current link is not broken. Obtaining a new care-of-address (CoA) and building a tunnel for packet forwarding make the fast handover scheme be able to reduce packet loss and handover latency. However, the performance of the fast handover scheme will be downgraded if a MN fails to finish the handover preparation before it disconnects. In this paper, we propose a reactive tunneling (RT) scheme to resolve the aforementioned problems. In the proposed RT scheme, MN can obtain a new Co A in advance and a tunnel is built with less overhead. As a result, the performance of fast handover scheme can be improved.
