The network lifetime is an important issue for employing wireless sensor networks in space and extreme environments. This is due to the fact that the sensing node energy is mainly consumed by transmissions. For maximizing the network lifetime in this paper a multi-hop clustering algorithm using the fuzzy logic improvement methods is introduced. The cluster heads nodes selection is based on four descriptors; residual energy as primary parameter, node proximity to its neighbors (centrality), distance to base station and node concentration.
