摘要
传统的云架构面临着网络负载过大、端到端延时长等问题。因此,利用基于雾架构的工业物联网通信机制与算法对传感数据进行采集处理,构建网络模型和能耗模型;选择期望传输能耗最小的节点作为转发器,通过雾服务器节点收集工业现场的传感数据;通过仿真实验将该通信机制与其他方法进行对比和评估。实验结果表明,该通信机制与算法可以有效收集工业现场的传感数据。能耗、第一死亡节点等指标比其他算法更具有优越性,为改善工业现场应用提供了新的解决思路。
The traditional cloud architecture faces problems such as excessive network load and long end-to-end delay.Therefore,we used industrial IoT communication mechanism and algorithm based on fog structure to collect and process sensor data,and built the network model and the energy consumption model.We selected the node with the lowest expected energy consumption as the transponder,and collected the sensor data of the industrial site through the fog server node.We compared and evaluated the communication mechanism with other methods through simulation experiments.The experimental results show that the communication mechanism and algorithm can effectively collect the sensor data of the industrial site.Energy consumption,the first dead node and other indicators are superior to other algorithms,which provides a new solution for improving industrial field applications.
