Energy Saving Based Target Coverage Algorithm in Wireless Sensor Network

To extend the lifetime of wireless sensor network and improve the efficiency of node energy, this paper puts forward redundant nodes sleep scheduling mechanism-based node energy-saving optimization coverage algorithm in wireless sensor network. Since current wireless sensor network coverage algorithm is high in energy consumption and redundant in nodes, the scheme takes networked coverage ratio, residue energy and redundant degree of WSN as the optimization target, sets up particle swarm optimization model, adopts crossover mutation operator and enhances algorithm optimization ability. The simulation results show that our algorithm improves the energy utilization efficiency, maintains the networked coverage rate, effectively extends networked life cycle and achieves the object of energy-saving optimization coverage.
