A few works have addressed fog application scheduling for hybrid MFC environments that consist of both iFog and mFog nodes. However, existing frameworks for mFog either designed for a specific purpose, such as for data routing in SDN [28], or for process/task distribution [20, 64], have not considered all the contextual factors (see Section 1.5.2) and the heterogeneity factors (see Section 1.5.1). Specifically, besides the movement of the entities, the tenants' application scheduling scheme should consider that the fog servers have the different computational and networking performance at different time slot due to the hardware specifications and the runtime context factors. In other words, developers need to have insight into the processing delay by considering all the factors toward proposing the optimal application scheduling scheme.
