Dynamic voltage scaling in wireless sensor network based on wavelet
基于小波的DVS在无线传感器网络中的应用

In order to extend life of wireless sensor network by making economical use of energy, put forward an effective method of dynamic voltage scaling which is based on wavelet, aimed at the node of wireless sensor network in running state to resolve it.Used wavelet, Kalman filter and AR to forecast the workload which next period will be, and what processors operating frequency levels(the work voltage and the operating frequency of CPU are one by one) is judged to enter according to the forecast results, the smaller task, the smaller operating frequency using, thereby reducing the energy consumption of nodes in one period. Experimental results show that the method is effective.
