| Outline of Final Research Achievements |
By understanding the characteristics of resonance phenomena between users and networks and linking them to the stable operation technology of the system, we had the following results.
First, considering the asymmetry of the strength of interaction among users, an oscillation model on networks has been introduced for a directed graph of a specific class. In doing so, it became clear that the oscillation energy of each node gives an extension of the concept of node centricity. In addition, we have extended the oscillation model to a general directed graph, model "flaming" as a phenomenon of oscillation energy divergence, and clarified its countermeasure method.
Second, we have evaluated the load concentration such as the flash cloud occurring between the user and the server by experiment using the subject, and we have modeled by using the proposed oscillation model.
