Fuente: Wipo "IOT" The present invention relates to an IoT technology, and more specifically, to a definition of basic distributed social group configuration of IoTs required for the IoTs to autonomously collaborate with each other by using a distributed social network, and a method thereof. According to one embodiment of the present invention, provided is a method of forming a basic distributed social group of semantic web-based IoT devices, and the method comprises: a step of allowing a new IoT device to access the basic social group made of a plurality of IoT devices; a step of allowing the new IoT device to check an IP address thereof; a step of allowing the IoT device to communicate with a plurality of IoT device forming a basic social group to search for an IoT device having a higher IP address which is the closest to IP address thereof; a step of registering the searched IoT device as a higher IoT device; a step of communicating with the plurality of IoT devices forming the basic social group and searching for an IoT device having a lower IP address which is the closest to IP address thereof; a step of registering the searched IoT device as a lower IoT device; and a step of forming the basic distributed social group with the new IoT device, and the higher IoT device and the lower IoT device, which are searched. Accordingly, the present invention can search for and collaborate with partners through social networks and can prevent load concentration on a central server. COPYRIGHT KIPO 2021
