| Outline of Annual Research Achievements |
1. We have proposed a novel cooperative jamming scheme for mmWave ad hoc networks with direct transmissions. Secrecy transmission analysis and optimization were also conducted. This research can be readily extended to mmWave cellular networks. The results of this research demonstrate the great potentials of the features of the mmWave links in achieving the physical layer security. Through this research, we produced one journal paper, which is now under revision.
2. We have proposed two physical layer security-aware buffer-aided relaying schemes for two-hop microwave wireless networks, which lay the foundation for the research in mmWave network of the next year. This work produced one international conference paper and one journal paper.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
In the plan of the first year, we focused on the scenario with direct mmWave links. Three issues will be addressed including cooperative jamming design, secrecy transmission capacity (STC) analysis and system STC optimization. All the three issues were addressed.
In addition to the research planed in the first year, I have also finished part of the research in the second year, including relay selection design and security-delay trade-off. The reason for progressing more smoothly than initially planned is due to our solid research background in previous studies in two-hop wireless networks. Although the part of research finished for the second year is for microwave wave communications, the results will also serve as good starting points for the research in mmWave scenairos.

| Strategy for Future Research Activity |
In the FY2020, I will continue the research as follows.
1. Extend the buffer-aided relaying schemes, which were designed for conventional microwave cellular networks, to the partial cellular coverage scenario as planed in the grant proposal.
2. Investigate the physical layer security in hybrid networks, where microwave communications coexist with mmWave communications. Although this is beyond the scope of the grant proposal, it deserves a dedicated study and will facilitate the promotion of the research plan.

| Causes of Carryover |
Reason: I was planning to use up the money planned for this fiscal year. But due to the breakout of the corona virus, the conference was cancelled and I have to use the remaining money next fiscal year.
Usage Plan: I am planning to attend international/domestic conferences or visit some researchers for information collection. Besides, I also need to buy some computers for simulations and numerical calculations. I am also planning to hire some students to help me conduct simulations and numerical calculations.
