Cluster head election with a fuzzy algorithm for wireless sensor networks

Focusing on large-scale wireless sensor networks, this paper introduces the idea of fuzzy logic according to the nodes´ residual energy, communication range, computing power, neighbor nodes, etc. Using fuzzy comprehensive evaluation method in virtual cluster head selection and the formation of the wireless network hierarchy overcome the randomness of cluster head election in LEACH protocol and uneven distribution of node energy; at the same time, generating the cluster node consequence through network initialization reduces the energy consumption when network constantly selects the cluster head and prolongs the life cycle of wireless sensor network.
