The present application discloses a method and an apparatus for network self-organization. The method comprises: a first node determining a second node of one or more transmission nodes according to a preset condition, the second node being a transmission node having the highest transmission level of the one or more transmission nodes, wherein a higher transmission level of a transmission node indicates fewer hops between the transmission node and an anchor node; and the first node establishing a connection to the second node. Thereby, each transmission node selects an appropriate node from a plurality of nodes on the basis of levels of different nodes and requests to establish a connection, thus realizing establishment of connections between different transmission nodes.
