FIG. 8 is a graph comparing response times between a distributed inter-device collaboration system according to the present invention and a conventional centralized inter-device collaboration system.

Referring to FIG. 8, the test was performed while increasing the number of data requests from 10 to 50, and the response time was measured. In the case of the centralized inter-device collaboration system, the average response time according to the number of requested tasks is 0.6 seconds, and the bottleneck frequently occurs as the requested task increases. That is, it was confirmed that the response time becomes longer as the number of requests is increased. On the other hand, in the distributed inter-device collaboration system according to the embodiment of the present invention, the average response time is 0.1 second, which is about 0.5 second shorter than that of the centralized inter-device collaboration system. This is because the server side device and the client side device are in 1: 1 communication and the other devices are waiting until they are connected to the server.
