In this paper, the authors has focused to raising the network lifetime of three stage based TSEP heterogeneous protocol of WSNs using the five stage heterogeneity level and also by using the hard and soft thresholding. The residual of the energies of the sensor nodes have used to get the optimum cluster heads. It doesn't necessitate any world wide data of energy at any time through the duration of WSNs. When cluster head establishment is finished, the CH communicates binary threshold picked by applying the HS values, i.e. Hard Threshold (HT) and Soft Threshold (ST).
