摘　　要：根据无线传感器网络自身能源有限的特点,采用能量模型优化策略对整个网络的能量消耗进行研究。网络能耗的实时监测是无线传感器网络研究的内容之一。首先对传感器节点的硬件整体架构进行分析研究,并对运行过程中各个工作模块的运行情况进行统计。通过对统计数据的分析,构建了有效的网络能耗模型。根据该模型,提出了一种无线传感器节点能耗监测算法,设计了基于TinyOS2.x的能耗仿真模块。为了验证和评估该算法的准确性,采用TinyOS2.x的仿真平台TOSSIM对网络能耗进行测试,并对仿真数据和真实数据进行对比分析。对比结果表明,该算法能够较为准确地实现对网络节点能耗的监测。Wireless sensor network（ WSN） is limited in its own energy resources,and the energy model optimization strategy is adopted to research the energy consumption of the whole network,thus,energy monitoring of the network in real time has become one of the contents to be researched. The overall hardware structure of the sensor node is analyzed and researched,and the statistics of operating conditions of each module are conducted. Through analyzing and studying the statistical data,an effective energy consumption model is established. The monitoring algorithm of energy consumption of the wireless sensor node based on the model is proposed,and simulation module of energy consumption based on TinyOS2. x is designed. This provides better solution for real time monitoring of the network energy consumption. In order to verify and evaluate the accuracy of the algorithm,experiments of network energy consumption are conducted on TOSSIM simulation platform of TinyOS2. x and real hardware environment. The simulation data are compared with real data,the result shows that the algorithm can monitor the energy consumption of network nodes more accurately.
