 Abstract: With the immense growth of Internet of Things (IoT) applications, traditional cloud computing is inadequate for handling the massive data volumes generated by IoT sensors and devices. Consequently, Fog and Mist computing paradigms have been adopted to address transmission latency issues. Fog computing extends cloud capabilities to the network edge, closer to the data generation points, thereby meeting low-latency requirements. Mist computing, a lighter version of fog computing, brings these capabilities even closer to the IoT layer. Since most IoT applications are near real-time and must meet deadlines, adopting efficient scheduling schemes in these environments is crucial. This ensures timely workload execution and maximizes the potential of cloud, fog, and mist computing systems. This keynote will explore emerging trends driving the development and cooperation of these computing paradigms. Additionally, we will present and discuss innovative techniques to address the challenges of resource allocation and scheduling in cloud, fog, and mist computing environments.
