APPARATUS AND METHOD FOR ROUING MULTICAST IN WIRELESS MESH NETWORK

摘要

The present invention relates to a multicast routing apparatus in a wireless mesh network and a method thereof. The multicast routing apparatus in the wireless mesh network includes an information obtaining unit which obtains the group ID information of adjacent mesh stations corresponding to each mesh station, a selecting unit which selects a multicast rertansmission set corresponding to the set of the mesh stations to participate in the retransmission of a multicast data packet using the group ID information, a tree generating unit which generates a tree corresponding to the transmission path of the multicast data packet, and a packet transmitting unit which transmits the data packet from a transmission mesh station to a reception mesh station among the mesh stations using the tree.
