Abstract
The invention discloses a three-stage sensing topology method and system based on the Internet of Things, and the method comprises the steps: building a DFS at a first stage of the three-stage sensingtopology method based on the Internet of Things, so as to search all simple routes; in the second stage, the AHPs based on pairwise comparison are suitable for analyzing qualitative and quantitativefactors needing to be considered so as to improve the experience quality of the Internet of Things system technology. Furthermore, related weights of these factors are obtained to enable the methods of the present disclosure to focus on those factors that are preferentially improved in a resource-limited environment. In the third stage, the TOPSIS based on the weight derived from the AHP is used for selecting the route with the optimal similarity measurement from all simple routes obtained from the proposed DFS, the system effectively reduces power consumption and improves the successful signal transmission probability to improve the service quality of the Internet of Things, the topology running time consumption cost is reduced, and a better Internet of Things environment is provided.
