Clustering Nodes Selection Mechanism in Energy Heterogeneous Farmland Wireless Sensor Networks
Dayong Liu, Chunjiang Zhao, Huarui Wu, Feifei Li · 2016
Solar-powered nodes have been employed in farmland wireless sensor networks to prolong the lifetime, which can increase the cost at the same time.The energy acquisition mode of solar-powered node is intermittent and nonlinear, because it is easy to be influenced by the external factors.In this paper, a fuzzy prediction method of the solar energy using the weather forecast is proposed, and then a fuzzy selection method to distinguish the different types of nodes is proposed.Simulation results show that the proposed method can improve the network throughput and reduce the energy consumption of nodes.
