Abstract (en)

[origin: WO2007138056A1] The present invention discloses a method for increasing handoff speed of a mobile node in wireless LAN, which comprises determining the handoff mode and a new access point when the mobile node needs handoff and performing handoff to the new access point based on the determined handoff mode. The present invention further discloses a mobile node, which comprises an access point information storage module, an access point selection module, and a handoff performing module. The handoff speed of the mobile node in wireless LAN can be effectively improved by using the present invention.
