Media access control method for wireless Mesh network

The invention provides a media access control method for a wireless Mesh network. A media access control (MAC) layer selects a cooperative node for nodes of each hop in an optimal path; and the cooperative nodes perform cooperative transmission in a data transmission process, and introduce dual busy tone to regulate rights of use of a channel. In the method, certain cooperative gain is obtained in a way of selecting the cooperative nodes for two-hop cooperative transmission; and the dual busy tone is adopted to control rights of possession of the channel, so a hidden terminal problem and an exposed terminal problem are better solved, and the overall performance of a network is greatly improved.
