A Generative Model for Shadowing in Urban Networks

27 Jan 2015

WNCG Prof. François Baccelli and X. Zhang have proposed a new model for shadowing. This model, which is based on the Poisson-Manhattan line process, generates correlated and log-normal shadowing fields. In a paper to be presented at INFOCOM 2015, this model is used for the analysis of urban wireless networks, where the locations of the nodes and the shadowing are known to be highly correlated. This shadowing model is tractable in that the distribution of the interference observed at a typical location and the joint distribution at different locations have closed form expressions. When applied to cellular networks, this model also leads to closed form expressions for spectral efficiency. More generally, this model captures important features of urban wireless networks, which cannot be analyzed using existing shadowing models.
