| Outline of Final Research Achievements |
The first outcome is a feasibility study of our proposed scheme, HayACK. In our proposed scheme, communication packets flow in a pattern that is not seen in ordinary communication transmission schemes. Therefore, there is a risk that communication may be interrupted by communication devices in the middle of the network. We have investigated how many communication paths actually block irregular packets in the current situation.
The second result is an investigation of the impact of our proposed scheme on existing schemes. Conventional fairness metrics do not handle the situation we envisioned well. By using the HARM indicator, we found that the impact of our proposed scheme on existing schemes is negligible.
