Recently, UAV-based wireless relay systems have attracted attention as a means of constructing substitute or complementary networks during communication network failures or traffic fluctuations caused by disasters, large-scale events, and other situations. Although UAV relay communication can rapidly and flexibly provide service coverage, relay positions must be controlled by considering not only user locations but also the surrounding radio propagation environment when users are moving. Cyber-Physical Systems (CPSs) have been utilized to design and evaluate such complex networks including mobile wireless stations. These approaches import three-dimensional map models into a CPS server and evaluate communication link quality using Ray-tracing (RT) simulations. However, conventional CPS systems have mainly been used for offline design and evaluation, making it difficult to control relay positions according to the state of an actually flying UAV station.
To address this issue, our research group proposed a UAV relay position control method using a CPS with real-time RT simulation capability. This paper conducts outdoor flight experiments on a university campus and shows that CPS-coordinated relay position control of a UAV station can significantly improve the stability of communication links for mobile users.
