A new fuzzy method for clustering heterogeneous nodes in Wireless Sensor Networks (WSNs)

Abstract. A Wireless Sensor network (WSN) contains a considerable number of sensor nodes and one base station where information is received through sensors and sent to base station. Sending information by each node to station reduces node energy and, accordingly, network lifespan due to distributed nodes and their various intervals. Thus, each node sends its data to neighboring cluster head in order to send the information to base station through that node and more energy is saved. Therefore, clustering and selecting appropriate cluster head is a topic which can be effective on network lifespan. Many different methods were introduced to cluster nodes in these networks with their own advantages and disadvantages. In this article, a new fuzzy logic-based clustering method in WSN increases the network lifespan.
