Prolonged lifetime is the one of the important requirement in Wireless Sensor Network (WSN). As communication is the major cause of energy depletion in the network so designing of energy efficient routing algorithm is one of the key challenges that need to be address for extending life time of network. In this paper we have taken the deployed redundant nodes in to account which cover major fraction of energy depletion in the network. We presents energy efficient routing algorithm, Dynamic Multi-cluster based upon the frame work of LEACH. In LEACH there are several nodes they monitor the same event thus provide the redundant information which is discarded by the cluster head before transmit it base station. This will cause major fraction of energy depletion in WSN. This redundancy of deployed nodes can be used as an advantage for increasing network life time. To our presented scheme we simulate it using Matlab. Simulation results show that Dynamic multicluster had outperformed LEACH on the basis of Network life time.
