摘要
针对电力物联网接入层可能面临设备并发接入引起的拥塞延迟问题,运用排队论的相关理论,对电力物联网接入层网络流量进行建模及参数分析。通过使用蒙特卡罗方法对模型进行计算,得出了物联网边缘代理在应对并发连接状况所要满足的性能指标。最后借助OPNET仿真软件,以ZigBee协议进行终端接入模拟,验证了所给出的流量模型和性能参数的有效性。
Aiming at the congestion delay caused by the connected layer of the power IoT,this paper models and analyzes the network traffic of the power IoT access layer based on the queuing theory.The performance metrics to be met by IoT edge agents in dealing with the condition of the concurrent connection are derived by using the Monte Carlo method.Finally,with the help of OPNET simulation software,the terminal access simulation is carried out with ZigBee protocol,and the validity of the traffic model and performance parameters given in this paper is verified.
