Fitting determinantal point processes to macro base station deployments
Résumé
The he macro base station (BS) deployments in modern
cellular networks are neither regular nor completely random.
We use determinantal point process (DPP) models to study the
repulsiveness among macro base stations observed in cellular
networks. Three DPP models are fitted to base station location
data sets from two major US cities. Hypothesis testing is used
to validate the goodness-of-fit for these DPP models. Based on
performance metrics including the K-function, the L-function and
coverage probability, DPP models are shown to be accurate in
modeling real BS deployments. On the contrary, the Poisson point
process and perturbed hexagonal grid model are shown to be
less realistic. Different DPP models are compared, and several
computational properties of these models are also discussed
