Abstract：
Stochastic geometry has been used as a powerful and useful tool in modeling of wireless communications for decades. However, most research papers consider base station (BS) distributions as homogeneous Poisson point process (PPP). In reality, most distributions of BS are displaying spatial correlations, i.e., repulsiveness or attractiveness, which leads to non-PPP based modeling. Non-PPP based modeling is usually not mathematically tractable though it is more accurate in capturing the correlation between BS locations. In this talk, I will present a new methodology, i.e., inhomogeneous double thinning (IDT) methodology, which has both good mathematical tractability and accuracy. Different metrics are studied, such as coverage probability, mean interference to signal ratio (MISR), and meta distribution. Then it is applied to realistic BS deployments, using datasets from Paris and Brussels, with special focus on not only coverage performance, but also EMF exposure distribution. The second part consists of modeling 5G massive MIMO networks, considering both realistic fitting of array patterns and channel fading. More perspectives will be given on the potential applications of stochastic geometry in different types of wireless networks, such as cognitive radio, satellite communications.
