IETF Mobile IP version 6 and its fast handover protocol provide transport layer connection survivability when a node moves from one Access Router to another by selecting a new care-of address (NCoA) instead of changing the home address. The aDAD(advance Duplicate Address Detection) protocol can almost eliminate the latency needed for the address configuration and confirmation from the whole IPv6 handover latency, but uses excessively a lot of network resources, such as bandwidth and IO load, to generate NCoAs and check their uniqueness. This paper proposes Agent-based DAD, a novel approach for efficiently provisioning NCoAs. The proposed scheme can reduce the required network resources significantly for generating these NCoAs, and keeping their uniqueness but does not change the basic behavior of aDAD.
