To improve the network coverage and communication capability of Internet of Things terminals,an adaptive node deployment method based on FFT algorithm for the Internet of Things terminal network is proposed.Firstly,according to the characteristics of the adaptive node deployment of the Internet of Things terminal network,the coverage of the Internet of Things terminal network is calculated.Then,the communication threshold is introduced to control the virtual force between adaptive nodes in a reasonable range to ensure that the terminal network of the Internet of Things is in a stable state.Finally,based on this,the FFT transform algorithm is used to construct the virtual force function model and introduce the basis function matrix to optimize the virtual power between the adaptive nodes to achieve the object.Optimized deployment of adaptive nodes for networked terminal networks.The simulation results show that The proposed method can significantly increase the number of effective nodes and network coverage,and significantly reduce the energy consumption of nodes.
