%X 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.
