Wireless Sensor Networks (WSN) find wide applications in defense, environmental monitoring like temperature, pressure, vibration, moisture, industrial monitoring, medical monitoring, habitat surveillance etc. The application of WSN consists of small sensor nodes that are low-cost, low power and multi-functional. The most important task of WSN is to send the collected data to the sink node and minimize the energy consumed during data transport. Sensor nodes forming a sensor network usually have limited energy capacity so it is important to minimize sensor nodes' energy consumption because of difficulty in supplying additional energy for the sensor nodes. This paper proposes an optimization of energy consumption in wireless sensor networks.
