无线传感器网络已经被广泛应用在各个领域。本文针对降低传感器节点能耗,延长电池使用时间做了一些硬件设计和程序设计的介绍;并建立休眠时间与能耗之间数学模型,定量分析两者关系。同时,结合试验结果,表明应用此预测模型可以为设计者提供一个简单的电池使用时长估算。 Wireless sensor networks have been widely used in various fields. In this paper, some hardware design and program design are introduced to reduce the energy consumption of sensor nodes and extend the battery life. The mathematical model between dormancy time and energy consumption is established to quantitatively analyze the relationship between the two. At the same time, combined with the test results show that the application of this prediction model can provide designers with a simple estimate of battery life.
