摘　　要：针对当前无线传感器网络能耗模型计算复杂、通用性差及理论模型与实际相差较大等问题,提出一种ZigBee无线传感器网络节点的能耗模型。采用无线传感器网络节点工作电压、发送状态、接收状态中各阶段的时长和工作电流以及休眠状态的工作电压和工作电流等参数,建立无线传感器网络节点处于发送状态、接收状态和休眠状态的能耗数学模型,进而建立无线传感器网络节点的总能耗数学模型。实验结果表明,该模型能够准确预测无线传感器网络节点传输能耗代价和剩余工作寿命。To solve current energy consumption model＇s drawbacks of a large amount of computation,poor universality and large differ- ence between theoretical model and actual situation,the model of node energy consumption based on ZigBee protocol is proposed. These parameters, including working current, working voltage, time duration of data sending and receiving, etc, are used to establish node energy consumption model in different states. The node working state is divided into the sending state, the receiving state and the dormant state. Then the total node energy consumption model could be built. The experiment results show that it can precisely predict the transmission energy consumption cost and the remaining life.
