Comparative study of hierarchy energy protocol in wireless sensor network

The Comparative Study of three main energy efficient wireless sensor networks (WSNs) protocols are studied according to their working. The WSN protocols are Low Energy Adaptive Clustering Hierarchy (LEACH), Power-Efficient Gathering in Sensor Information System (PEGASIS) and Threshold Sensitive Energy Efficient Sensor Network (TEEN). These three protocols work on hierarchical structure to succeed their own functioning and improvement energy efficiency. Here include four quality of services (QOS) parameter performance namely “Average End to End Delay”, “Average Energy Consumption”, “Packet Delivery Ratio” and “Throughput” which are developed and compare to their QOS parameter performance. At the end of the analysis, design an overall study for these protocols with respect to their QOS parameter and further generalized the future scope of this study.
