摘　　要：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。One of the study hotspots nowadays is how to have efficient power management to economize energy. An energy-efficient schedule for WSN based on AR model was proposed, which improves on heightening forecasting precision and reducing transmitted data. An unequal space AR model was put forward. A conclusion through emulation mode was reached that the data sent by this way are less than two-thirds of those using real time monitor.
