英文摘要：

To reduce the power consumption of device, dynamic power management prediction strategies based on the structure of adap- tive learning tree is researched. Through added idle-time length node in the structure model of Probability-based adaptive learning tree, an improved Prediction Strategies on the strength of Probability statistics weighted idle-time is proposed, the idle-time length is used as pro- jections and based on the probability statistics of actual historical state, the idle-time predicted result is updated. Results of the simulation indicated the proposed method can effectively lower power consumption and improve the prediction accuracy.
