Efficiency of energy is a major design purpose in the majority of the study associated to wireless sensor networks as the nodes are rigorously energy controlled. In this research paper, improvement in the performance of the HEER has been shown using improved fuzzy based cluster head selection. The HEER has used a variety of probability function for cluster head selection for choosing the best cluster head by using the residual energy. The fuzzy cost has been evaluated on the basis of the residual energy and the node centrality. The fuzzy cost is dynamic in nature as it has been evaluated in every round. Thus it has provided better results due to its adaptive nature i.e. have change as the residual energy varies. The benefit of the proposed protocol is that the optimum numbers of clusters are formed in every round, which is almost impossible in LEACH and also not guaranteed in HEER. The main goal of this work is to enhance the average energy consumption, packets send to base station and packet sent to cluster head by using the integrated HEER protocol which will enhance the network life time by using thresholding and if then rules based algorithm and optimum size cluster formation mechanisms.
