The invention provides a new networking method for a wireless sensor network, which adopts a mixed networking method of Mesh and clustered topology. The method comprises four devices of sink nodes, backbone nodes, cluster-head nodes and cluster-member nodes, wherein, the backbone nodes form a systematic backbone network through Mesh topology structure, and other nodes carry out networking according to the clustered topology form and are divided into the cluster-head nodes and the cluster-member nodes, wherein, a plurality of cluster-member nodes are under the management of the cluster-head nodes which are also responsible for reporting to the backbone nodes; a plurality of the cluster-head nodes are under the management of the backbone nodes. The three kinds of nodes of the backbone nodes, the cluster-head nodes and the cluster-member nodes carry out networking interactively through distributed information. Collection nodes are mainly responsible for the collection of network sensor data and part of network management work. By virtue of the mixed networking method of Mesh and clustered topology, the new networking method of the invention can fully utilize the conductivity of the Mesh network and reciprocal multi-hop communication, and the advantages of the clustered structure in energy saving and management, thereby effectively realizing the state management, sleep management and data transmission of the nodes in the wireless sensor network at a relatively large scale.
