配电物联网（PDIOT）面临着海量接入和日益复杂的任务。PDIoT需要配置大量的计算资源，并建立相应的资源管理策略，以管理海量访问和及时处理任务。本文提出了基于PDIoT的云边缘系统来解决上述问题，并针对其性能分析的需求，提出了一种仿真软件EdgeCloudSim来对PDIoT进行建模。首先，分析了PDIoT建模的关键要素，包括云边缘架构和任务处理。云边缘架构是计算资源的载体，而任务处理则包括任务请求的上传、任务的处理和指令的下载。然后，研究了利用EdgeCloudSim对PDIoT进行建模的方法。EdgeCloudSim具有模块化架构。因此，通过在某个模块中调整参数或编辑功能，可以对所需的PDIoT进行建模。最后，在仿真中设置了故障处理场景和三种不同的任务卸载策略。仿真结果验证了EdgeCloudSim的有效性。
The Power Distribution Internet of Thing (PDIoT) is faced with mass access and increasingly complicated tasks. To manage mass access and timely process tasks, PDIoT needs to configure plenty of computing resources and set up corresponding resource management strategy. In this paper, PDIoT based cloud-edge system is applied to solve the above problem, and with the requirement to analyse its performance, a simulation software EdgeCloudSim is proposed to model such PDIoT. Firstly, the key elements of PDIoT modelling, including cloud-edge architecture and task processing are analysed. Cloud-edge architecture is the carrier of computing resources, while task processing consists of uploading task requests, processing tasks and downloading instructions. Then, the methods to model PDIoT by EdgeCloudSim are researched. EdgeCloudSim has a modular architecture. Thus, by tuning parameter or editing function in a certain modular, a wanted PDIoT can be modelled. Finally, a fault handling scenario and three different task offloading strategies are set in simulation. The simulation result verifies the effectiveness of EdgeCloudSim.
