- Abstract
- This paper specifies access router based movement detection using L2 information and care-of address (CoA) configuration for fast handover in mobile IPv6. An access router which serves a mobile node performs movement detection, formulates a new CoA of the mobile node and does duplicate address detection (DAD) on behalf of the mobile node. After confirming the uniqueness of a new CoA, an access router sends it through a router advertisement (RA) message. Since an access router can quickly determine 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, 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 a new CoA for its interface directly.
