Increasing life-time of wireless sensor network using energy-efficient and fault tolerance algorithms

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 (LEACH) protocol by three algorithms. The first focuses selecting best cluster head second minimizing required nodes within same cluster. Simultaneously, third fault tolerance algorithm uses software engineering techniques like sleep schedules increase network lifetime testing results prove claim enhancing WSN. In order check improvement we have compered with standered algorthim. show life-time WSN, where total rise from about 550 rounds reach 4100 when utilized self-checking process rised up 5200 after minimum distans.
