Title
Grid-Based Design For The 3d Primary Exclusive Region In Uav Networks
Abstract
This paper proposes a design for a primary exclusive region (PER) based on a cylindrical grid model in unmanned aerial vehicle (UAV) networks. UAV communications require using additional frequency bands shared with other systems. When they use these bands, their communications must not interfere with the communications of the primary users (e.g., radar systems). To avoid this interference, a PER should be designed. This paper proposes a complex-shaped PER design based on the radar's antenna pattern to maximize the number of transmitting UAVs, and presents a stochastic geometry analysis of interference in UAV networks. On the assumption that the distribution of UAVs in each grid follows an inhomogeneous Poisson point process, the radar's outage probability is derived. From this analysis, an optimization problem of PER is formulated to maximize the number of transmitting UAVs. Subsequently, the solution of this problem is numerically evaluated for a keyhole antenna model. The results show that the complex-shaped PER is designed corresponding to the radar's antenna pattern and the number of transmitting UAVs increases with an increase in the number of grid divisions.
