如何进行有效的功率管理以节省能量是当今无线传感器网络的研究热点。文中提出的基于AR模型的无线传感器网络节能策略在提高预测精度和减少数据发送量上做出了改进,并给出了非等间距AR模型的算法。通过仿真得到,使用本文算法的传感器节点所需发送的数据量不到实时监测的传感器节点所需发送数据量的三分之二。
How to carry on the effective power management in order to save the energy is the research hot spot of the wireless sensor network nowadays. The AR model-based energy-saving strategy for wireless sensor networks proposed in this paper has been improved in improving the prediction accuracy and reducing the amount of data sent, and an algorithm for non-equally spaced AR models is given. Simulation results show that the sensor nodes using this algorithm need less than two-thirds of the data to be transmitted by the sensor nodes that are monitored in real-time.
