A method for controlling an upload size of data by a device is provided. The method includes determining whether to change a size of data to be uploaded based on a policy of an upload target server, upon determining to change the size of the data to be uploaded, determining an initial transfer size of the data, and uploading a part of the data corresponding to the determined initial transfer size, updating an upload result of the partial data in an upload history, and determining a next transfer size for the data depending on a reception result of the part of the data from the upload target server for a period obtained from the policy.

Method and apparatus for controlling upload size of device

The present disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method includes acquiring a shared address for at least one file stored at a cloud storage server upon detecting that the at least one file needs to be backed up, determining at least one other cloud storage server to which the at least one file will be backed up, and transmitting a backup request message including the shared address to the at least one other cloud storage server.

A method of controlling multiple street lamps with a mobile terminal includes receiving event information regarding a street lamp, among the multiple street lamps, from a gateway via an Internet in real-time. The event information indicates that a predetermined event has occurred in the street lamp. Notification information indicating that the event information has been received, is provided to a user of the mobile terminal in real-time. A control instruction for controlling the first street lamp based on control information input by the user, is transmitted to the first street lamp.

A cyclone used in a separator apparatus includes a body and a vortex finder. The body includes an inlet passageway, a cylindrical passageway connected to the inlet passageway, and a conical passageway connected to the cylindrical passageway. The cylindrical passageway has an upper end through which first particles in a fluid are exhausted, and a lower end. The conical passageway has an upper end connected to the lower end of the cylindrical passageway, and an opened lower end through which second particles having a specific gravity greater than that of the first particle are exhausted. The vortex finder is connected to the upper end of the cylindrical passageway. A first exhaust passageway is vertically formed in the vortex finder so that the first particles spirally ascend through the first exhaust passageway from the cylindrical passageway.
