摘要
通过对网络能耗模型的分析,综合网络能耗方程和终止条件,建立了一种定量预测传感器网络寿命模型。建立了单个节点稳态能耗速率时间序列ARMA模型,通过最小二乘法预测能耗趋势,提出了应用于实际系统的寿命预测计算方法。利用该方法,对应用LEACH协议和HEED协议的传感器网络进行了寿命预测仿真。实验结果表明,模型和计算方法达到了预期的寿命预测效果。
To build the foundations for research on energy-efficient protocols, by the analysis of network energy consumption model, a quantitative sensor network lifetime model combined network energy consumption equation and the terminating conditions is presented. By ARMA model of single node energy dissipation rate and prediction process, a practical computational method is achieved. And simulations on sensor networks lifetime via LEACH and HEED protocols are provided. The experimental results show that the model and calculation method achieve the desired results.
