摘　　要：针对基于理论模型的感知节点能耗研究通常仅考虑部件能耗、缺少从节点整体上分析与评估系统能耗问题的现状,通过分析节点部件在状态运行以及状态变迁时的能耗状况;基于状态转移的矩阵建模方式建立部件能耗模型;基于事件触发机制明确系统主要能耗部件之间的关联,建立节点整体的能耗模型。在OPNET上仿真验证了本模型的可靠性及实用性。仿真结果证明,本模型可为节点选型、协议评测以及网络构建分析提供模型支持和理论指导。The energy-consumption models are now almost deduced from the theoretical model,only taking the communication module and processor into account without an overall analysis and assessment for the energy-consumption of nodal system.Based on the matrix modeling of state transition,this paper analyzed the energy consumption within all states and between the state transitions,and established their energy-consumption models respectively,and then revealed the energy consumption features of node modules.Moreover,considering in event-driven mechanism,this paper established a unified energy-consumption model by defining a clear correlation among the modules of a node,and then tested the reliability and usefulness of this model in the OPNET.The simulation results show this energy-consumption model can provide theoretical guidance for component selection,protocol evaluation as well as network analysis
