Abstract: The latest evolution in Information Technology has led to the appearance of the Cloud-to-Thing Continuum, which combine the Internet of Things (IoT), Cloud Computing and Fog Computing. IoT systems are composed of possibly up to billions of smart devices, sensors and actuators connected through the Internet, and these components continuously generate large amounts of data. Cloud and fog services assist the data processing and storage needs of IoT applications, while Blockchain services can support accountability and verification of certain actions. The location and behaviour of IoT devices can change dynamically, which calls for multicriteria optimization methods to be applied during the execution of these applications. The investigation and detailed analysis of such application and their underlying complex systems can be fostered by simulation solutions.
The DISSECT-CF-Fog simulator can be used to model a complex IoT-Fog-Cloud infrastructure, and a generic IoT application on top of it. It also supports the analysis of arbitrary actuator events and mobility capabilities of IoT devices in IoT-Fog-Cloud systems. The main metrics it considers for system analysis: execution time, resource/network usage, energy usage, and service pricing.
This talk presents a general overview of the simulation capabilities of the DISSECT-CF-Fog simulator, and discusses them through various application scenarios. It recent development directions will also be presented, which are triggered by the issues raised by the Swarmchestrate EU-funded research project. It aims to combine emerging technologies to create a completely decentralised autonomous and self-organised application management system suitable to manage hyperdistributed applications that span across different layers of the dynamic compute continuum.
