### Stochastic Geometry: Wireless Modeling

In an Infocom'15 paper, F. Baccelli and X. Zhang (Qualcomm) have introduced an analytically tractable stochastic geometry model for urban wireless networks, where the locations of the nodes and the shadowing are highly correlated and different path loss functions can be applied to line-of-sight (LOS) and non-line-of-sight (NLOS) links.

Using a distance-based LOS path loss model and a blockage (shadowing)-based NLOS path loss model, one can derive the distribution of the interference observed at a typical location and the joint distribution at different locations of the network. When applied to cellular networks, this model leads to tractable coverage probabilities (SINR distribution) expressions. This model captures important features of urban wireless networks, which were difficult to analyze using existing models.

This model was lately extended in a joint work by the same authors and Robert Heath (UT Austin) in a paper presented at IEEE Globecom'15 where it received the best paper award.
