A Versatile Dependent Model for Heterogeneous Cellular Networks

Executive Summary

Due to the increasing spatial irregularity of cellular systems, point process models are ideally suited for analysis and simulation. When modeling multiple tiers, including macro-, micro-, and femto-tiers, a natural choice is the superposition of independent Poisson Point Processes (PPPs), each one modeling the locations of the base stations of a particular tier. The authors propose a new model for heterogeneous cellular networks that incorporates dependencies between the layers. In particular, it places lower-tier base stations at locations that are poorly covered by the macrocells, and it includes a small-cell model for the case where the goal is to enhance network capacity.
