Method and apparatus for grouping mobile nodes in extended wireless LAN

摘要

A method and apparatus for grouping wireless access points and re-grouping access points separated from a group in order to construct a clear and efficient transmission connection channel in an extended wireless LAN architecture are provided. Accordingly, a grouped mobile node (513) determines disconnection of a connection channel to the group, and if the connection channel is disconnected, the mobile node (513) searches for a connection channel to the existing group or a new group to re-subscribe thereto, so that all the mobile nodes can always be in a grouped state. As a result, it is possible to prevent broadcast storm in which broadcasted frames are repetitively transmitted along a loop in an extended wireless LAN architecture.
