Mobile devices have several restrictions due to design choices that guarantee their mobility. A way of surpassing such limitations is utilize cloud servers called cloudlets on the edge network through Edge Computing. However, as number clients and grows, service must also increase its scalability in order a latency limit quality threshold. This can be achieved by deploying activating more cloudlets, but this solution expensive cost physical servers. The best choice optimize resources an...
