MOBILE NODE FOR SUPPORTING LOSSLESS HANDOVER AND METHOD FOR LOSSLESS HANDOVER BY USING THE SAME

PURPOSE: A mobile node for supporting lossless handover and a lossless handover method using the same are provided to reduce handover latency and prevent data loss. CONSTITUTION: A signal strength measurer(120) measures strength of a beacon signal transmitted from access points adjacent to a connected access point. According to the strength of the beacon signal, the signal strength measurer generates an L2 trigger. When the L2 trigger is generated, a controller(150) selects an access point which transmits the strongest signal strength among the beacon signals as an access point in which handover is realized. The controller changes a BSSID(Basic Service Set ID) part of a header of a data packet stored in a Tx queue(140) into a BSSID of the access point in which handover is realized.
