摘　　要：针对无线传感器网络的节点在运行状态提出了动态电压调度(DVS)算法。DVS是通过改变处理器的工作电压和工作频率来减少处理器的消耗能量。该方法首先必须对节点各部分发出的信号进行分析和预测,并根据预测后的信号对处理器设定处理速率,最后,设定合适的工作电压和工作频率。Aimed at the node of wireless sensor network in running state an effective method of dynamic voltage scaling（DVS） is put forward. DVS algorithms reduce energy consumption by changing frequency and voltage of processor, in this technique, the signals which are emitted by every part of the node are analysed and forecasted, and then enactment the manage speed for processor based on the forecasted signal, a appropriate working voltage and working frequency is enactmented.
