- Abstract
- This paper specifies access router based movement detection and care-of address configuration for fast handover in Mobile IPv6. An access router which will serve a mobile node performs movement detection, formulates a new CoA of the mobile node and does duplicate address detection behalf of the mobile node. After confirming the uniqueness of the new CoA, the access router sends it through a RA message. Since an access router can quickly determine the L3 movement by the comparison between neighbor caches and L2 information of a mobile node, a mobile node does not have to wait to receive RA messages from access routers. Thus, the movement detection delay is reduced. Since DAD is performed by an access router in advance, a mobile node does not have to do normal DAD and it can use the new CoA for its interface directly.
