| 摘 要： | 无线传感器节点一般由电池供电,且电池不易更换,所以传感器网络最关注的问题是如何高效地利用有限的能量.动态电压调节技术允许软件在运行时动态的改变处理器的频率和电压,以减少它的能量消耗.分析了现有的一些动态电压调节算法,根据无线传感器网络多跳路由和拓扑易变化的特点,提出了一种针对中继节点的动态电压调节算法,并在NS2平台上对算法进行了仿真.通过对仿真结果的分析,表明改进的算法能够很好地减少系统能量消耗,延长无线传感器网络的使用寿命.

| Abstract: | A wireless sensor node is typically battery operated and the battery is not easy to replace,so how to use its limited energy effectively is the most important thing concerned by wireless sensor network(WSN).Dynamic voltage scaling(DVS) can reduce the energy consumption of the processor by allowing software to dynamically vary the voltage and frequency of the processor.This paper has analyzed some existing DVS algorithms and presents a DVS algorithm about relay nodes according to multihop routing and topolog... |
