In the wireless mesh networks, identification of nodes does not need to set the address, only take the manufacturing time of the node as the sequence to identify. Nodes in the query and data transmission adopt a master - slave mode. The center node initializes slave-node according to the node of the manufacturing time sequence, through the search command, search to find the slave-node. The newly found node recursive search is for the next batch of nodes. Eventually form a wireless mesh network. Center nodes and the nodes of data communication are made by mesh network.
