Edge computing system and method for recommending connection device

A method for recommending a connection device by an IoT server, the method comprising:

• storing device information received from multiple electronic devices;
• receiving a device registration request from a first electronic device;
• generating first recommendation information including a list of at least one electronic device, which is connectable to the first electronic device through edge computing, among the multiple electronic devices, based on the stored device information;
• transmitting the first recommendation information to the first electronic device;
• receiving, from the first electronic device, operation state information of the at least one electronic device included in the first recommendation information;
• and
• based on the operation state information, generating second recommendation information including a list of at least one external device which is connectable to the first electronic device through the edge computing, or receiving the second recommendation information from the first electronic device.

A method for recommending a connection device by an electronic device, the method comprising:

• transmitting device information of the electronic device to an external server;
• receiving, from the external server, first recommendation information including a list of at least one external device which is connectable to the electronic device through edge computing;
• requesting transmission of operation state information from the at least one external device included in the first recommendation information;
• acquiring the operation state information of the at least one external device, and
• based on the operation state information of the at least one external device, acquiring second recommendation information including a list of at least one external device to be connected through edge computing.
