1: 当初の計画以上に進展している
理由
In the plan of the second year, we focused on the scenario with partial cellular coverage scenario, which can be modeled as two-hop wireless transmissions. The three research tasks including the design of relay selection scheme, the secrecy performance analysis and the modeling of the delay-security tradeoff were all finished, thanks to the research achievements in the first year and the first half of the second year.
In the second half of the second year, we moved on to the research tasks of the final year, which focuses on the scenario without cellular coverage, i.e., totally ad hoc networks, and proposed two PLS schemes for (mobile) mmWave ad hoc networks. We also analyzed the STC performances, which is part of the final year's research tasks.

| 今後の研究の推進方策 |
In the final year, We will continue our research as planned.
(1) We keep focusing on the scenario of totally ad-hoc mmWave networks and will design secure routing protocols to ensure secure end-to-end transmissions.
(2) Based on the theoretical analysis in the second year, we will analyze the end-to-end STC and delay performances of the concerned networks.
(3) The STC-delay tradeoff will also be addressed.

| 次年度使用額が生じた理由 |
Due to the pandemic of CoVID-19, all the international conferences I planned to attend were cancelled and changed to be held online. That's why I spent 0 yen for the travel expense, and as a result, 651,213 yen were left and will be used next year to cover the registration fee of international conferences, the page charge of journal papers and the purchase fee of equipments and (electronic) books.
