Abstract

In this paper, we focus on ultra-dense network modeling
where both the Base Stations (BSs) and Mobile Terminals
(MTs) are UAVs. In this case, two communication nodes can
be very close to each other. However, existing cellular network
analyses typically use the standard unbounded path loss model
where received power decays like r^beta over a distance r. This
standard model is a good approximation for the path-loss in
wireless communications over large values of r but is not valid
for small values of r due to the singularity at 0. This model is often
used along with a random uniform node distribution, even though
in a group of uniformly distributed nodes some may be arbitrarily
close to one another, thus, it will lose accuracy and may be
not applicable for UAV-to-UAV communications. To tackle this
problem, by using mathematical tool behind stochastic geometry,
we propose tractable analytical frameworks of coverage and rate
based on the novel unbounded path-loss model with a constant
distance factor r_0 for analyzing the UAV-to-UAV communications.
