要約(英語): Fog-Cloud computing system has recently attracted much attention. This system has a simple three-tiered hierarchy: Network edge, Fog, and Cloud. Network edge includes IoT (Internet of Things) devices. Fog is localized computing facilities including network devices such as an edge router, a switch and any other. In this system, Fog handles various data processing, which are sensitive to delay, to shorten WAN propagation latency arising from the location of Cloud. However, if the data processing is concentrated on Fog, the delay of the processing and power consumption of the network edge may increase rather than Cloud computing. The reason why is because Fog has more limited resources than Cloud. Therefore, we should decide an appropriate allocation of roles between Fog and Cloud taking the latency of the processing and the power consumption of the network edge into account. In this paper, we consider the design of Fog-Cloud computing taking the latency and cost resulted from the power consumption into account by using a mixed integer linear programming.
