Abstract: “Wireless sensor networks are the networks that can sense, calculate and then communicate the data. To collect the data at sensor nodes consumes a lot of energy but sensor nodes are energy constraint. In this paper we will discuss an algorithm, which is energy efficient by transmission of minimum number of reference data, (i.e. minimum number of reference data transmission) number of bits required to transmit that data will also reduced and by placement of nodes in the network in such a position that the distribution of energy will balance. It will provide efficient energy consumption in case of node failure also.”
