In distributed sensor networks, a large number of small sensors are deployed to create a network which cooperates together to set up a sensing network. The main duty of sensors is to prepare access to environmental information anytime, anywhere by collecting, processing, analyzing and transmitting data. Scalability, load balancing and increasing network lifetime are significant parameters for wireless sensor networks [1]. Clustering is a useful technique to address these issues. In this paper, we propose a distributed, energy-efficient, fault tolerant and weighted clustering algorithm that extends the network lifetime by using some parameters such as energy, centrality, density, in addition distances between nodes and the base station. We consider a backup node for each cluster, that will be replaced while the cluster head drain out of its energy, and also cluster head list [2] for every node. These mechanisms cause increasing the network lifetime and lead the network to become fault tolerant.
