Analysis And Measurement Of Power Consumption In Wireless Sensor Networks Nodes

Energy consumption is a key issue in Wireless Sensor Networks （WSN）, which determines lifetime of the networks Power consumption of nodes in WSN was analyzed from its hardware components, operating mechanism, computational complexity and data communication capacity etc. Power consumption models of modules were established, the characteristics of node＇s currents and measure techniques of low power consumption were studied, and a measurement system of nodes was designed to validate its low-power characteristics. All of these means are to analyze and solve the problem of energy consumption in WSN, to ensure the validity of energy management.
