无线传感器网络节点的低功耗设计

无线传感器网络(WSNs)能够协作地实时监测、感知和采集各种环境对象的信息,并将信息传递给系统用户主机进行分析处理。节点具有感知和路由的功能,在实际的应用中,功耗是影响节点工作寿命的关键因素。设计分析了WSNs系统功率消耗的构成,并从硬件和软件方面提出和总结了WSNs的低功耗设计方法,设计了一种低功耗的WSNs节点,并进行了测试,结果证明:该方法适合WSNs节点的应用,具有易使用、低功耗特点。

Low power consumption design for wireless sensor networks nodes

Wireless sensor networks(WSNs)which can monitor perceive and gather real-times various information of environment collaboratively and the signals is sent to the host computer for processing.The nodes of WSNs serve the functions of perceiving and routing.Power consumption is the key factor affecting the longevity nodes in practice.The power consumption of WSNs is designed and analyzed.Some methods are given from hardware and software aspects to reduce the sensor power consumption.A low power consumption WSNs nodes are designed and tested.Experment results show that the method has low power consumption,easy to use and other advantages.
