物联网(IoT)系统正变得越来越复杂、异构性和普及性，使用不同的连接类型集成了跨架构层(云、雾、边缘)分布的各种物理设备和虚拟服务。因此，这种系统的研究和设计已被证明是具有挑战性的。尽管物联网研究大量涌入，基于模拟的方法在支持研究方面也有显著优势，但普遍缺乏适当的建模和仿真平台来创建端到端物联网服务的详细表示，即从底层物联网节点到云中的应用层以及底层网络基础设施。为了帮助研究人员和实践者克服这些挑战，我们提出了IoTNetSim，一个新颖的自含式可扩展的端到端物联网服务建模和仿真平台。该平台支持对异构物联网节点(传感器、执行器、网关等)进行建模。具有精细的细节(移动性、能源配置文件等)以及不同的应用逻辑和网络连接模型。建议的工作与当前的文献不同，它是一个端到端物联网服务的一体化工具，具有多层体系结构，允许对具有不同结构的物联网系统进行建模。我们使用来自自然环境和灾害监控物联网领域的两个非常大规模的真实案例对我们的IoTNetSim实施进行了实验验证和评估。
Internet-of-Things (IoT) systems are becoming increasingly complex, heterogeneous and pervasive, integrating a variety of physical devices and virtual services that are spread across architecture layers (cloud, fog, edge) using different connection types. As such, research and design of such systems have proven to be challenging. Despite the influx in IoT research and the significant benefits of simulation-based approaches in supporting research, there is a general lack of appropriate modelling and simulation platforms to create a detailed representation of end-to-end IoT services, i.e. from the underlying IoT nodes to the application layer in the cloud along with the underlying networking infrastructure. To aid researchers and practitioners in overcoming these challenges, we propose IoTNetSim, a novel self-contained extendable platform for modelling and simulation of end-to-end IoT services. The platform supports modelling heterogeneous IoT nodes (sensors, actuators, gateways, etc.) with their fine-grained details (mobility, energy profile, etc.), as well as different models of application logic and network connectivity. The proposed work is distinct from the current literature, being an all-in-one tool for end-to-end IoT services with a multi-layered architecture that allows modelling IoT systems with different structures. We experimentally validate and evaluate our IoTNetSim implementation using two very large-scale real-world cases from the natural environment and disaster monitoring IoT domains.
