Review Paper on Enhancement of Least Fault Clustering Protocol to Reduce Energy Consumption in Wireless Sensor Nodes

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 we 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. The WSNs are not ready to handle this type of situations in overall lifetime. In this paper we introduce a survey on the access of fault tolerance and its location in clustering protocol or we studied the methods of detecting and recovering faults. And the main thing is by using low energy protocols we have to send the information in an effective way from upper level to base station means one end to another end.
