Consistent networking method based on ISA100.11a standard

The invention discloses a consistent networking method based on an ISA100.11a standard. The method comprises the steps of ignoring function difference of all wireless devices, carrying out collectionand statistics on single-hop wireless communication quality of a whole grid network topology through a system manager and taking the single-hop wireless communication quality as point-to-point weightin the topology; evaluating the weight and generating unconnected complex network topology graphs; forming a fully-connected new graph through utilization of a backbone router and the unconnected complex network topology graphs of all wireless devices; marking the weight of all added sides starting from the backbone router as 1; solving the minimum spanning tree by taking the backbone router as aroot node; extracting the out-degree of the root node of the minimum spanning tree, setting the out-degree as K, wherein the least number of trees contained by the unconnected complex network topologygraphs is equal to a K valu
