Abstract: Through the analysis of the node energy attenuation, this paper uses energy attenuation forecast model to describe the law of energy consumption. The reporting mechanism based on the forecast model is set up, which can significantly reduce the reporting counts, data traffics in netsworks and node consumption. Experimental results show the working time of Telosb node can expend 1%~4.5% after using this forecast model.

摘要： 分析节点能量衰减的过程，采用节点能量衰减预测模型描述节点能量损耗的规律，并建立基于该预测模型的节点剩余能量汇报机制，从而减少节点能量数据的汇报次数以及节点间的数据通信量，降低节点能耗。实验结果表明，在应用该预测模型后，Telosb节点的电池工作寿命延长1%~4.5%。
