Abstract: Due to the recent technological advancements such as the Internet of Things (IoT) and the development of smart environments, traditional Cloud computing is insufficient in transferring a huge volume of data generated by IoT devices. As a result, Fog and Mist computing have been established as computing paradigms to solve problems related to network bandwidth, transmission latency and security. The majority of the IoT applications typically require processing in a real-time manner and the target is to ensure that all deadlines are met. Therefore, it is necessary to employ appropriate scheduling techniques, in order to exploit the full potential of cloud, fog and mist computing systems and to achieve the required quality of service level.

The objective of this keynote talk is to present potential research directions driving the development of new computing platforms. Furthermore, novel techniques to explore challenges in scheduling of time critical applications in cloud, fog and mist computing architectures will be provided and discussed.
