Energy-efficiency ofwireless sensor networks (WSN) becomes an essential issue in the research area. This is because of energy constraints WSN that depend on a battery, which difficult to replace or recharge; therefore, multiple clustering algorithms were proposed achieve efficiency using available as much possible. paper energy-efficient and fault-tolerance enhance thelow adaptive hierarchy (LE...
