Interference and Outage in Clustered Wireless Ad Hoc Networks

In the analysis of large random wireless networks, the underlying node distribution is almost ubiquitously assumed to be the homogeneous Poisson point process. In this paper, the node locations are assumed to form a Poisson clustered process on the plane. The authors derive the distributional properties of the interference and provide upper and lower bounds for its CCDF. They consider the probability of successful transmission in an interference limited channel when fading is modeled as Rayleigh. They provide a numerically integrable expression for the outage probability and closed-form upper and lower bounds. They show that when the transmitter-receiver distance is large, the success probability is greater than that of a Poisson arrangement.
