A Wireless Sensor Network is the collection of large number of sensor nodes, which are economically feasible and measure the ambient condition in the environment surrounding them. The difference between ordinary wireless networks and WSNs is that sensors are sensitive to energy utilization. Energy saving is the essential issue in designing the wireless sensor networks. In this paper the protocol called Kmedoids-LEACH protocol (K-LEACH) for clustered WSN is aimed to prolonging the lifetime of sensor networks by balancing the energy consumption of the nodes. The protocol uses the Kmedoids clustering algorithm for uniform clustering. Euclidean distance and Maximum Residual Energy (MRE) is used to select the Cluster Head (CH).This protocol is used to enhance the lifetime of the network. To address the problem of how to control the failure of Cluster Head (CH) in network, the proposed work carries Vice Cluster Head (VCH) selection algorithm to allow the node that will become a VCH of the cluster in case of CH dies. By doing this, cluster nodes data will always reach base station in an efficient way and no need to elect a new CH at each time if the CH dies. This will extend the overall network life time.
