The embodiment of the invention discloses a distributed network topology control method and a node thereof, which belongs to the communication field. The method comprises the following steps: a node acquires a mark and a characterization quantity of a one-way link from other node to the node; a weight value of an edge is acquired according to the mark and the characterization quantity of the one-way link acquired by the node, and a mark and a characterization quantity of a one-way link broadcast by other node and received by the node; a tree-shaped communicating topology is generated; and a logic neighboring node is determined. The embodiment of the invention calculates the characterization quantity of the one-way link with the node as a target through each node in network, and also receives a plurality of characterization quantities of one-way links with other nodes as the targets broadcast by other nodes to acquire the weight values of a plurality of edges so as to generate a communicating topology meeting the preset conditions. The embodiment of the invention has the advantages of effectively reducing the interference in the data transmission process, reducing collision possibility caused by MAC competition and improving the effect of actual performance of network.
