Wireless Sensor Networks formed by grouping of small batteries equipped sensor nodes, faces the major issue in optimization of energy when designing the routing protocols.Clustering based routing algorithm proved energy efficiency in Wireless Sensor Networks (WSNs), in which appropriate cluster formation and cluster heads (CHs) selection is crucial for energy saving.Thus, this paper proposes an approach which uses fuzzy C-Means (FCM) in cluster formation and uses the three parameters for cluster head selection: the new energy parameter considered threshold value, the residual energy of each node and the distance from node to base station (BS).FCM algorithm creates uniform clusters in the network area and reduces the distances between each node and their corresponding cluster head node.The proposed clustering protocol can give longer network lifetime when it is implemented in MATLAB simulation environment and compared to LEACH.Simulation results tell that the proposed protocol overcome the performance of LEACH protocol in terms of saving energy and reducing dead nodes to prolong the network lifetime.
