Comparative Analysis of Simulators for IoT Applications in Fog/Cloud Computing

In order to make people's life easier, a significant number of Internet of Things (IoT) applications have become a part of a global world. The internet of things is strongly intertwined to cloud computing, and sensor data handling is one of the most urgent issues with cloud computing. Sensors and other cloud-connected smart devices are frequently used to operate IoT-Cloud systems; as a result, these devices generate a large volume of data that must be preserved and processed efficiently. Simulators have the advantage of allowing complex systems to be explored without the requirement to purchase and install physical resources. The purpose of this article is to look at several cloud implementation simulators and see which ones are best for today's IoT demands. With the moving of the trend and computing needs, this paper provides a brief examination of the different most widely used simulators in the research field by categorising the simulators into three categories: cloud, edge, and fog simulators. Finally, various future research direction in accordance with the simulator's evolution is given.
