In order to solve the problem of too many data categories in wireless sensor networks,the similar information parameters are integrated into an independent cluster object set,and an adaptive clustering algorithm for wireless sensor network data based on improved PSO is proposed.According to the mechanism of the improved PSO algorithm,the calculation value of Euclidean distance index is determined to realize the processing of network data.In the system of wireless sensor networks,the principle of clustering and sorting is defined,and the adaptive expected entropy is solved in combination with relevant data samples to complete the research of adaptive clustering algorithm for wireless sensor network data.The experimental results show that under the effect of the improved PSO algorithm,the number of cluster object sets after the integration of wireless sensor network data is reduced from 20 to 6,which can solve the problem of too complex data class items in wireless sensor network and meet the practical application requirements of integrating similar information parameters on demand.
