Abstract

The Network shadowing (NeSH) model is accurate in approximating the correlations between links in wireless networks, but the computational complexity is high. Based on the NeSH model, this paper proposes an elliptical overlap (EO) model. The shadowing region of each link is modeled as an ellipse, and the correlation coefficient of two links is computed by approximating the area of the intersection of the two corresponding ellipses. EO model decreases the time cost greatly, while improves the precision.
