MCC uses computational augmentation approaches (computations are executed remotely instead of on the device) by which resource-constraint mobile devices can utilize computational resources of varied cloud-based resources.<ref name=":0" /> In MCC, there are four types of cloud-based resources, namely distant immobile clouds, proximate immobile computing entities, proximate mobile computing entities, and hybrid (combination of the other three model).<ref name=":0" /><ref name="Khan 42–49"/> Giant clouds such as Amazon EC2 are in the distant immobile groups whereas [[cloudlet]] or surrogates are member of proximate immobile computing entities. Smartphones, tablets, handheld devices, and wearable computing devices are part of the third group of cloud-based resources which is proximate mobile computing entities.<ref name="Khan 42–49"/><ref>{{cite journal|last=Fernando|first=Niroshinie|author2=Seng W.
