In order to solve the energy consumption problem of wireless sensor network,a novel energy consumption method is proposed based on Gaussian Pseudo Spectral Method.In this model,Hausdorff distance between wireless sensor clusters and the relationship between energy consumption and distance of data transmission are firstly given,and the calculation method of energy consumption of cluster head node is established.Then,the energy consumption model is solved with Gaussian Pseudo Potential Method.Finally,the key factors influencing the model are deeply studied through the simulation experiment.The experimental results show that,compared with other algorithms,the model has a great advantage in terms of residual energy,false positive rate,energy consumption,and network life.
