    Abstract: An apparatus, method and system are provided for routing a broadcast data frame in a mesh network with multiple mesh portals. In the mesh network, every mesh point selects and registers its default mesh portal. A mesh portal enters its address in a destination address field of a broadcast data frame received from outside of the mesh network and broadcasts the data frame to inside of the mesh network. The mesh point processes a received broadcast data frame relating to its registered mesh portal, thereby preventing the broadcast data frame from being redundantly transmitted in the mesh network.

    Abstract: A method and apparatus for controlling power of a transmitter in a mesh network. A controller, if it sets a reference power to one of a first measured transmission power and a maximum power, compares the reference power with a first power in level, and compares the first power with a second power in level. A cumulation factor calculator calculates a cumulation factor by comparing the first power with the second power. A reference power setter sets the reference power according to a scope to which a value obtained by adding a reference power to a sum of the calculated cumulation factors belongs. A power controller controls transmission power according to the set reference power.
