“…There are a number of studies of wireless signal strengths for correlated shadow variables, see references in [Szyszkowicz et al, 2010], but general results of the type presented here are virtually unprecedented. Perhaps closest to our limit results are those of [Szyszkowicz and Yanikomeroglu, 2014] where a limit theorem is shown for the sum of the signal spectrum from a finite (but large) collection of transmitters assuming a specific transmitter layout and shadowing correlation function that is much less general than our setting.…”

We consider the point process of signal strengths emitted from transmitters in a wireless network and observed at a fixed position. In our model, transmitters are placed deterministically or randomly according to a hard core or Poisson point process and signals are subjected to power law propagation loss and random propagation effects that may be correlated between transmitters.We provide bounds on the distance between the point process of signal strengths and a Poisson process with the same mean measure, assuming correlated log-normal shadowing. For "strong shadowing" and moderate correlations, we find that the signal strengths are close to a Poisson process, generalizing a recently shown analogous result for independent shadowing.

“…Reference [1] summarizes the state of the art on correlated shadowing models based on parametric path-loss functions of relative/absolute propagation distance and incidence angle. Reference [2] discusses the approach based on correlated log-normal shadowing random variable. All these prior models maintain the analytical tractability at the cost of missing the geometric features of blockages.…”

This paper proposes a cascade blockage model for analyzing the vision that a user has of a wireless network. This model, inspired by the classical multiplicative cascade models, has a radial structure meant to analyze blockages seen by the receiver at the origin in different angular sectors. The main novelty is that it is based on the geometry of obstacles and takes the joint blockage phenomenon into account.We show on a couple of simple instances that the Laplace transforms of total interference satisfies a functional equation that can be solved efficiently by an iterative scheme. This is used to analyze the coverage probability of the receiver and the effect of blockage correlation and penetration loss in both dense and sparse blockage environments. Furthermore, this model is used to investigate the effect of blockage correlation on user beamforming techniques. Another functional equation and its associated iterative algorithm are proposed to derive the coverage performance of the best beam selection in this context. In addition, the conditional coverage probability is also derived to evaluate the effect of beam switching. The results not only show that beam selection is quite efficient for multi-beam terminals, but also show how the correlation brought by blockages can be leveraged to accelerate beam sweeping and pairing.

“…The study in [30] extends the statistical analysis of interference for arbitrarily-shaped areas. When the point where the interference statistics are collected is located outside of the area generating the interference, e.g., primary-secondary system set-up, the moments of interference (also cross-moments) can be well-approximated using integration [31], [32].…”

In this paper, we study the receiver performance with physical layer security in a Poisson field of interferers. We compare the performance in two deployment scenarios: (i) the receiver is located at the corner of a quadrant, (ii) the receiver is located in the infinite plane. When the channel state information (CSI) of the eavesdropper is not available at the transmitter, we calculate the probability of secure connectivity using the Wyner coding scheme, and we show that hiding the receiver at the corner is beneficial at high rates of the transmitted codewords and detrimental at low transmission rates. When the CSI is available, we show that the average secrecy capacity is higher when the receiver is located at the corner, even if the intensity of interferers in this case is four times higher than the intensity of interferers in the bulk. Therefore boundaries can also be used as a secrecy enhancement technique for high data rate applications.
