Wireless sensor networks consists of thousands of tiny, low cost, low power and multifunctional sensor nodes where each sensor node has very low battery life. Main goal is to conserve the transmitted energy from various sensor nodes. Various energy efficient algorithms have been designed for this. LEACH uses distributed cluster formation & randomized rotation of the cluster head to minimize the network energy consumption. The authors' paper proposes an algorithm which is the enhancement of existing improved and balanced LEACH. It reduces the energy consumption by using various energy bank acts as saving or energy nodes.
