The present invention relates to the field of WSN routing protocol, provides a high-performance communication method based on WSN improved routing protocol, and solves the problem that the existing routing protocol cannot take into account the average network energy consumption and the comprehensiveness of the cluster head node to the network in the wireless communication process of WSN coverage problem. The technical solution mainly includes treating all nodes in the network as a data point set S, and calculating the straight-line distance value d between all data points ij , the entire distance interval is divided into each distance interval according to the increment of the unit increment, and the number of data points distributed in each distance interval in the statistics is x i After calculating the median value of all distance intervals, use it for fitting, apply the probability model to the fitting result, and find the adaptive parameter K; calculate the adaptive cut-off distance d according to the adaptive parameter K ci It is used to calculate the local density ρ of each data point, and calculate the distance parameter δ according to the size relationship of the local density ρ i ; put ρ i *δ i as a selection indicator for cluster centers.
Description
A High-performance Communication Method Based on WSN Improved Routing Protocol technical field [0001] The present invention relates to the field of routing protocols, and provides a high-performance communication method based on WSN improved routing protocols. Background technique Wireless Sensor Networks (WSN) is a wireless A multi-hop self-organizing distributed sensor network can be constructed without relying on any given structure, so Its settings are flexible and the device location can be changed at any time. Compared with traditional networks and other sensors, WSN has the It has the characteristics of free mode, non-centralized control mode, dynamic network topology and so on. Nowadays, wireless sensor networks have been widely used in It is used in many fields such as disaster forecasting, national defense and military, environmental monitoring, etc., and has huge market application prospects. [0003] WSN mainly includes three parts: node, sensor network...
