The present disclosure relates to a technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and the Internet of Things (IoT). The present disclosure can be utilized in an intelligent service (such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related services) based on the technology. A gateway device according to the present disclosure determines whether additional power consumption information on an electronic device is needed, makes a request for the additional power consumption information to a smart plug when the additional power consumption information is determined to be necessary, determines the maximum number of smart plugs capable of transmitting the additional power consumption information to the gateway device, and controls data transmission of at least a part of smart plugs transmitting the additional power consumption information to the gateway device.

Method and device for detecting electronic device connected to smart plug

A method and an apparatus for validating device-to-device (D2D) communication devices in a server via a mobile terminal are provided. A 1st device-to-device (D2D) communication device includes a communication unit for communicating with a mobile terminal via D2D communication, and a controller. The controller is configured to control the communication unit to transmit digital signature information of the 1st D2D communication device to the mobile terminal, receive, when the digital signature information is successfully authenticated in a server, server public encryption information, from the mobile terminal, and transmit device information of the 1st D2D communication device, which is encrypted using the server public encryption information, to the server, and register the 1st D2D communication device in the server. The method and apparatus reduce user input for registering D2D communication devices in a server, increases user convenience, and decrease authentication time.
