摘要
为了提高智慧城市建设中物联网智能控制平台的工作效率和稳定性,提出一种基于改进蚁群算法的TSN调度算法,以物联网智能门户为通信内核,发送数据并执行控制指令。终端设备通过MQTT协议连接云端,进行数据通信。测试结果表明,改进蚁群算法的TSN调度算法能够解决时间敏感网络的消息调度问题。该算法的寻优效率和收敛速度都高于传统算法,并能有效避免陷入局部最优,且时延较短抖动变化稳定,从而确保时间敏感网络的实时性。
In order to improve the work efficiency and stability of the IOT intelligent control platform in the construction of smart cities,a TSN scheduling algorithm based on the improved ant colony algorithm is proposed.The IOT intelligent portal is used as the communication core to send data and execute control commands.The terminal device is connected to the cloud through the MQTT protocol for data communication.The experimental results show that the TSN scheduling algorithm based on the improved ant colony algorithm can solve the message scheduling problem in time-sensitive networks.The optimization efficiency and convergence speed of the algorithm are higher than those of the traditional algorithm,and it can effectively avoid falling into the local optimum,and the delay is short and the jitter change is stable,thus ensuring the real-time performance of the time-sensitive network.
