Outline of Final Research Achievements

In this research we proposed a user centric wireless communication systems that can provide high QoE (Quality of Experience) and high-level of physical layer security for user. Our proposed method is based on analysis of user preference and behavior analysis, and database based traffic prediction for various granularities of space and time. We validated the effectiveness of our algorithm by theoretical analysis, computer simulation, and experiments based on radio wave propagation.
