Abstract: In the 21st century, sensor system turns into a key range for exploration and development. Remote sensor nodes are employed as a part of numerous territories like farming, military, medicinal services and debacle administration and so on. Nowaday, it is finishing up exceptionally valuable for media transmission and system industry. In the remote sensor systems, sensor hubs, detects the physical condition and detected information is sent to the base-station. Sensor nodes are deployed on a geographical area where human intervention is not possible or very difficult. The researchers are using the clustering technique for enhancing the lifespan of wireless sensor network. The clustering is providing the solution for problem of hot-spot and is also used for balancing the load and scalability of the network. In recent times, various clustering algorithms are given by researchers for improving the lifespan of the sensor systems.
