ABSTRACT:
In this work, we studies the information-theoretic secrecy performance in large-scale cellular networks based on a stochastic geometric framework. The locations of both base stations and the mobile users are modeled as independent two-dimensional Poisson point processes. We consider two important features of cellular networks, namely, information exchange between base stations and cell association, to characterize their impact on the achievable secrecy rate of an arbitrary downlink transmission with a certain portion of the mobile users acting as potential eavesdroppers. In particular, tractable results are presented under diverse assumptions on the availability of eavesdroppersa location information at the serving base station, which captures the benefit from the exchange of the location information between base stations.
