This paper proposes a new fast handoff scheme for Mobile IPv6 based wireless networks. To implement the proposed scheme, the beacon message used in L2 is defined newly by adding a specific subfield to the capability information field. In addition, Router Information Request/Reply messages used in L3 are defined newly. The proposed scheme provides the faster acquisition of new access router's network information than the existing one, which might be advantageous for the low handoff latency. In addition, the proposed scheme might reduce amount of traffic in comparison with the existing one, which might be remarkable when there are many mobile nodes that are now connecting to current access router. Moreover, in the proposed scheme, a mobile node can know whether it changes access router or access point, which can remove redundant traffic of the existing one. Via extensive experiments, it will be shown that the proposed scheme outperforms existing ones in terms of the L3 handoff latency and the packet loss
