In order to reduce the energy consumption and prolong the network lifetime of wireless sensor networks(WSNs),an efficient multi-layer routing protocol through fuzzy logic based clustering mechanism(MLFC)for WSNs is proposed. The MLFC mainly includes three steps. First,the network is divided into several layers based on the relationship between communication distance and energy. Second,cluster headers are elected among layers through fuzzy logic according to node's remaining energy,distribution density and concentration. Nodes join the cluster formed by the nearest cluster headers. Third,data packets are transmitted to the base station layer by layer. A multihop routing is constructed. Experiment results show that the MLFC is of benefit to balance the nodes energy consumption and achieves an evident improvement of network lifetime.
