Wireless Sensor Networks (WSNs) have become popular due to their application in various fields such as home health care, military surveillance, and environmental science. For long-term and low-cost monitoring applications, Wireless Sensor Networks (WSNs) are commonly used. The key issue involved in wireless sensor networks is the energy efficiency of sensor nodes. Because nodes in WSN are powered by small irreplaceable and non rechargeable batteries. Existing paper efforts show that clustering is an efficient method to prolong the lifetime of WSN network.
