Recently the implementations of wireless sensor networks have developed immensely. There is one device which is used in Wireless Sensor Networks (WSNs) to increase the lifetime of the network and give very effective functioning process that is clustering. It is the process in which the whole section or part is divided into small parts which understand the domain of sensor network in the directions of clusters. A carrier or head is chosen by each cluster which is called as cluster head. In the cluster the cluster head is chosen by the sensor nodes. If the clustering is very effective then the users can save lots of energy in the network. The credibility of WSNs is influence by faults which is occurred by many reasons like if the hardware is in the defective manner, software defect and disruption.
