Abstract: In
the recent years, due to the exponential growth of the Internet of Things (IoT)
applications and the development of smart environments, the traditional Cloud
computing is insufficient for transferring the
huge volume of data generated by IoT devices. As a result, Fog and Mist
computing have appeared as new computing paradigms to
solve the problem of transmission latency by placing computations in the vicinity
of the IoT. Fog computing extends the cloud to the
network edge, closer to where the IoT data are generated. Mist computing is a
lightweight form of fog computing, that brings fog capabilities even closer
to the IoT layer. Typically, the IoT applications are time-critical and the
primary concern is meeting deadlines. Consequently, appropriate resource
allocation and scheduling policies are required to exploit the full potential
of cloud, fog and mist computing environments. In this keynote we will explore
research directions driving the development of these new computing paradigms.
Furthermore, novel techniques addressing the challenges in resource allocation and scheduling in cloud, fog and mist computing
environments will be presented and analysed. |
