Placement of IoT-based Application Services in Fog-Cloud Environments

What is it about?

Service Placement Problem (SPP) is the mapping of IoT services among fog and cloud resources. It plays a vital role in response time and energy consumption in fog-cloud environments. In this paper, we propose an efficient algorithm for solving SPP that provide high QoS for IoT services and energy efficiency for Fog Service Providers (FSPs). To achieve these goals, we classify services into two categories: critical services and normal ones. Our extensive simulation experiments show that our policy improves the energy consumption by up to 18%, the percentage of deadline satisfied services up to 14%, and the average response time up to 10% in comparison with the second-best results.
