Modelling Fog & Cloud Collaboration Methods on Large Scale

Fog Computing is expected to decentralize clouds to improve users quality of service, in technologies like the Internet of Things, by pushing some computing onto mini-clouds (called Fogs) located close to end users. To enhance M&S with this concept, we have developed a complete Fog/Cloud collaboration methods to conduct simulation experiments: Users manipulate their experiments though nearby Fogs servers while M&S resources are dynamically discovered and allocated throughout the Fogs/Cloud. We have already built those methods using privately owned clouds. However, it was difficult in practice to study those methods scalability using real system setups. As a result, we present here the simulation model that we developed to mimic this real system in order to study the proposed collaboration methods on large scale. This model was validated with reference to the real system. The results have clearly shown the scalability of those proposed methods at the structure and coordination levels.
