In order to optimize the data transmission characteristics of WSN networks,a stable transmission algorithm for ultra wideband in WSN based on redundancy screening control evaluation mechanism is designed.Based on the redundant transmission scheduling mechanism,the region is initially segmented,and the stable survival effect of regional clustering is quickly achieved through energy evaluation.Combined with the method of constructing energy thresholds for regional nodes,the clustering redundancy efficiency is increased to reduce the probability of node constraints under ultra wideband conditions.The regional boundary control method is adopted to enhance the efficiency of backbone nodes by optimizing their remaining energy,reduce the regional transmission jitter caused by backbone nodes first,and ensure the best performance of relay transmission nodes to reduce link jitter.Transmission nodes are selected based on their backbone node capabilities to enhance network link transmission capabilities and further reduce the adverse effects of jitter on transmission performance.Simulation experiments show that the algorithm proposed in this paper has lower cumulative jitter frequency of network links and higher network transmission bandwidth.
