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. Purpose 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 is proposing an algorithm which is the enhancement of existing IB-LEACH. It reduces the energy consumption by using energy bank. 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, ACTIVE_ROUTE_TIMEOUT is also enhanced by shamming the static parameters of HELLO_INTERVAL, RREQ_RETRIES and NET_DIAMETER. Results are compared through MATLAB and provide better approach than previous ones.
