This paper proposes a new Mobile IPv6 Fast Handover mechanism in IEEE 802.11 wireless networks with several access routers. To implement the proposed mechanism, the beacon message used in link layer is defined newly by adding a specific subfield to the capability information field. In addition, Router Table Request/Reply messages used in IP layer are defined newly. The proposed mechanism provides the faster acquisition of new access router's network information than the existing one, which might be advantageous for the low handover latency. In addition, the proposed mechanism 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 mechanism, a mobile node can know whether it changes access router or access point, which can remove redundant traffic of the existing one.
