Improving Life Time of Wireless Sensor Networks by Using Fuzzy c-means Induced Clustering

Over the recent years, cluster-based hierarchical routing protocol is an important issue of the performance of the consumed WSN (wireless sensor network). Based on LEACH (Low-Energy Adaptive Clustering Hierarchy) algorithm, a new algorithm named FCM (Improving Life Time of Wireless Sensor Networks by Using Fuzzy c-means Induced Clustering) is proposed. We divided all nodes into Q clusters by the Fuzzy c-means algorithm and chose the cluster head according to the node´s energy and the distance between the center position of each cluster and base station in the first round. Then clusters will be fixed. In the new round begins, the choose of cluster head node is based on the current energy value and the distance to the base station in a cluster. During the data transmission, the communication took the single-hop in the cluster and multihop in inter-cluster. The simulation results showed that the algorithm was rational and efficient.
