A wireless sensor network (WSN) is a network consisting of wireless computing devices called sensors that sense environmental conditions like motion, sound, etc in an area. These networks collect the information from the environment and send it to the sink node. And these sensor nodes typically combine wireless radio transmitter, receiver and limited energy, restricted computational processing capacity and communication band width. The proposed algorithm used to select the cluster heads for transmission of data in the wireless sensor networks. The fitness function proposed in this algorithm to consider both the distance of the nodes from the base station and their energies and the network simulator NS-2 is proposed for simulation. The results show that the proposed protocol results in 4% of energy consumption and prolonged network lifetime compare to the existing which energy consumption is 8% and high energy consumption of the wireless sensor network.
