Abstract
The present invention discloses a wireless communication network comprising: at least one edge device coupled to a wired network; one or more wireless transport device coupled to the edge device via a wireless network; and at least one mobile device coupled to the wireless transport device via the wireless network. Wherein the wireless transport device carries an identify information of a neighboring device in a broadcast frames; and the identify information allowing the wireless transport device to determine to receive a broadcast frames from the neighboring device. The wireless transport device maintains and calculates a table that contains a list of couples of frame originator and the neighboring device the broadcast should come from. When the table includes the information of the neighboring device, the wireless transport device accepts the broadcast frames from the neighboring device while the table depicts the frame originated by the originator should come from the neighboring device. Otherwise, the wireless transport device drops the broadcast frames from the neighboring device.
