The client device is defined as the devices that demand remote computing resources from Cloud/Fog or Mist computing infrastructure. Computational resources required by the device complying with a set of restriction requirements $r = \left\{ (r_{1},r_{2},...,r_{k})\textrm{ } | \textrm{ } k \in \mathbb{N} \right\}$. As an illustration, we can show as examples of restriction requirements: minimum link speed; Run time; maximum latency and cost associated with the use of the resource. …show more content…
Represented in the model such as the set of vertexes: $$F = \left\{v_{i} \in U \textrm{ } | \textrm{ } i,n_{F} \in \mathbb{N}\textrm{ , } i \in \textrm{ }\left\{1,2,..,n_{F}\right\}
