Energy efficiency is recognized as a critical problem in Wireless Sensor Network (WSN). The routing in the WSN consumes more amount of energy, thus routing protocol for communication must be energy efficient. In energy efficient routing protocols the energy efficient path depletes quickly and an unbalanced distribution of energy among nodes may cause death of node or network. LEACH (Low Energy Adaptive Clustering Hierarchy) is a hierarchical-based routing protocol which uses random rotation of the nodes required to be the cluster-heads to evenly distribute energy consumption in the network.
