Measurement and Analysis to Wireless Sensor Network Node Energy Consumption
无线传感器网络节点能耗测量及分析

Energy efficiency of sensor network is the key problem in the wireless sensor network research and accurate measurement of node energy consumption is the basis for assessment.Existing methods for testing sensor network node energy are difficult to meet a long time,fine-grained and high-precision measurement needs.Therefore this paper designed a sensor network node energy measurement equipment which uses the energy measurement circuit composed by current sampling,high-speed AD conversion chip and programmable logic array to fulfill the accurate and continuous measurement of node function and do the next analysis for the measured results.Measured results show that the power measurement device complies with the actual sensor network node operation and the measured results provide the data basis for the energy consumption online assessment of sensor network node.
