A fast handoff method in mobile IPv6 using prerouting
In this paper, we propose a new fast handoff routing method, called fast handoff using prerouting, for mobile IPv6. The new routing method will improve the packet delay and save the bandwidth during handoff. It routes the packet to the destination before the mobile node finishes its route update to the corresponding node (CN). It can also save the bandwidth wasted in tunneling during route update to CN. Special agents attached to the access routers and border routers are proposed to help prerouting. The proposed fast handoff combines the benefits of cellular systems and data communication systems. The agent residing in the routers will act as an MSC in a cellular system and it takes care of mobile nodes in its wireless LAN. Simulation results demonstrate its efficiency compared to previous schemes. Copyright (C) 2006 John Wiley & Sons, Ltd.
