An efficient approach for clustering in wireless sensor network using fuzzy logic

Wireless sensor network(WSN) is composed of a large number of sensor nodes that are connected to each other to perform specific tasks. These nodes have limited energy, processing power and memory. Since the network lifetime depends on the nodes On, the power supply component in the nodes is very important. Therefore we need to use strategies to reduce energy consumption in the nodes. Clustering is one of the strategies to reduce energy consumption. Many clustering algorithms have been introduced. LEACH algorithm is one of the famous of them. In this paper we proposed an efficient method for clustering using fuzzy logic with appropriate inputs and combine it with the good features of LEACH. These method is fully distributed. Therefore its speed is more and its energy consumption is less than centralized methods. Also our proposed method will resolve the weaknesses of LEACH and is more efficient than the existing methods.
