There is tremendous increase in popularity of Wireless Sensor Network (WSN) as the sensor network connects the virtual world and physical world together. Sensors nodes can be deployed in hostile environment where there is no access of human beings. Sensor nodes rely on battery power where it becomes a difficult task to replace the battery. So to improve the networks energy is very important task. To overcome this problem, a routing protocol was proposed known as Low-Energy Adaptive Clustering Hierarchy (LEACH).
