Wireless sensor network (WSN) is composed of a large number of sensor nodes that are connected to each other. In order to collect more efficient information, wireless sensor networks are classified into groups. Classification is an efficient way to increase the lifetime of wireless sensor networks. In this network, devices have limited power processing and memory. Due to limited resources in wireless sensor networks, increasing lifetime was always of attention. An efficient routing method is called clustering based routing that finds optimum cluster heads and finding the correct number of them in each cluster remains a challenge. In this paper, we propose a novel and efficient method for clustering using fuzzy logic with four appropriate inputs and combine it with the good features of Low-Energy Adaptive Clustering Hierarchy (LEACH). Simulation results show that our method is more efficient compared to other distributed algorithms, because the proposed method if fully distributed. The result show that compared to centralized, the speed is more and its energy consumption is less.
