| Outline of Annual Research Achievements |
(1) We have proposed a Sight-based Cooperative Jamming scheme to improve the physical-layer security (PLS) performance of millimeter-wave (mmWave) ad hoc communications. We also developed a novel theoretical framework to analyze the secrecy transmission capacity (STC) performance under the scheme.
(2) We have proposed a novel security-aware Aloha protocol to improve the PLS performances of mobile ad hoc networks (MANETs). We also analyzed the STC performance of MANETs under the novel Aloha protocol.
Based on the above two achievements, we have published one international conference paper and two journal papers.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
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.

| Strategy for Future Research Activity |
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.

| Causes of Carryover |
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.
