摘要
能耗是LoRaWAN网络传感器节点设计和实现中最具约束性的要求之一,直接影响其使用寿命。文章提出了一种基于LoRaWAN技术A类终端设备的传感器节点能量分析模型,通过该模型划分传感器节点的工作序列和工作场景,从而计算得出传感器节点不同工作模式的能耗;通过分析影响能耗的关键因素,进而对其优化,延长使用寿命。
Energy consumption is one of the most restrictive requirements in the design and implementation of LoRaWAN sensor nodes,which directly affects their service life.In this paper,a sensor node energy analysis model based on LoRaWAN technology A terminal equipment is proposed.Through this model,the working sequence and working scene of sensor nodes are divided,and the energy consumption of different working modes of sensor nodes is calculated.By analyzing the key factors affecting energy consumption,the energy consumption is optimized and the service life is prolonged.
