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. Our paper propose 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. This energy bank stores the energy after each round in both routing and clustering phase which overall increases the life time of the network. In this approach, enhancement of IB-LEACH is done and results are compared through MATLA. Thsese results shows that enhanced IB-LEACH provide better approach than existing ones.
