Wireless Sensor Networks (WSNs) are broadly deployed for civil and military purposes. WSN is asensor network used to monitor physical and environmental conditions of a system such as a temperature, sound, andpressure. Sensors collect the data and send it to the desired destination such as base station. It consists of tiny nodeshaving very limited energy; once this energy ends then the node dies. Energy consumption is a major issue in thesesensor networks. Hence, the focus of this research is to make these sensors cheap and energy-efficient. In order to gainoptimized results, hundreds and thousands of nodes are deployed. To make the system more energy efficient, differentrouting techniques are used. In this paper, a new Efficient Time Division Multiple Access (TDMA)-based Clustering(ETC) Scheme for WSNs has been introduced which is more energy efficient than other schemes. ETC scheme usesclustering and TDMA by using hierarchy. In this hierarchy, nodes are divided into three levels, lower level nodes,medium level nodes and high energy nodes. Simulation results show that ETC has high energy efficiency, higherthroughput and lower end-to-end delay. ETC results have been compared with existing schemes like Modified Low-Energy Adaptive Clusturing Hierarchy (MODLEACH) and Low-Energy Adaptive Clusturing Hierarchy (LEACH)-CCH. ETC showed better results than these schemes. ETC was 2.13% better than Low-Energy Adaptive ClusturingHierarchy -CCH and Modified Low-Energy Adaptive Clusturing Hierarchy in case of throughput analysis. ETC hadless energy consumption than Low-Energy Adaptive Clusturing Hierarchy-CCH and Modified Low-Energy AdaptiveClusturing Hierarchy. ETC showed 2.29*104 joules of average energy consumption which was far better than Low-Energy Adaptive Clusturing Hierarchy-CCH which showed1.16*105 joules and Modified Low-Energy AdaptiveClusturing Hierarchywhich was 3.63*104 joules. In the end-to-end delay, ETC show much better results as comparedto Low-Energy Adaptive Clusturing Hierarchy-CCH and Modified Low-Energy Adaptive Clusturing Hierarchy.ETC showed 4.94*104 seconds of an end-to-end delay which was far better than Low-Energy Adaptive ClusturingHierarchy-CCH which shows 9*104 seconds and Modified Low-Energy Adaptive Clusturing Hierarchy which was6.66*104 seconds. It is shown from the results that ETC has high stability period and higher throughput.
