The Low-Energy Adaptive Clustering Hierarchy (LEACH) is an efficient routing algorithm designed for transmission in WSNs. This routing protocol is based on the hypothesis that there is an equal amount of energy in each sensor node,which is not a real-time practice. To manage the balanced energy utilization, LEACH adopts a TDMA based MAC protocol. The random data distribution amongst the nodes leads to the wastage of TDMA slots. There is a requirement for the amendments to the existing LEACH algorithm to utilize the slots corresponding to data-less nodes. Also, the proper energy utilization of sensor nodes and network lifetime enhancement is anessential topic in the research of WSNs. A novel method for LEACH WSN based on adequate cluster leader substitution and double power amplification is proposed in this research. This smart system saves the energy to be wasted in worthless cluster formation and the energy to be destroyed in routing packets to the new cluster leader. Apart from minimizing energy utilization in cluster formation, a concept of different energy amplification levels for various data transmission modeshas been introduced. This concept permits low energy levels for intracluster communications as compared to cluster leader to sink node transmission. The various output parameters, i.e.,alive nodes, dead nodes, packet transferred to the cluster leader, the packet transmitted to the sink node, and normalized Network’s average energy, are taken for experimental purposes. Also, the proposed method is compared with three existing methods. These methods are Double Cluster Based Energy Efficient Routing Protocol (DL-LEACH), Optimized LEACH (OP-LEACH), and Assistant Cluster Head clustering algorithm based on LEACH protocol (ACH LEACH).
