基于EWS的DVS在无线传感器网络中的应用
摘要
动态电压调度(DVS)通过使用EW S算法对任务量预测
并根据预测结果判断处理器该进入何种操作频率等级
使较小任务量使用较小的操作频率
从而减少了节点的能量消耗。仿真实验结果表明:该方法是有效的。
Abstract
An effective method of dynamic voltage scaling is put forward.Task quantity is forecasted by expected workload state(EWS) arithmetic.Operating frequency levels of processors is judged according to the forecast results.The smaller task quantity
the smaller operating frequency using;thereby the energy consumption of nodes is reduced.Experimental results show that the method is effective.
