  A significant portion of the 5th generation of wireless networks will operate
in the mm-wave bands. One of the several challenges associated with mm-wave
propagation is to overcome shadowing due to signal blockage caused by
environmental objects. Particularly susceptible are nodes in a device-to-device
network that typically operate at low power and in a blockage prone environment
such as crowded open areas. In this work, we provide an insight into the effect
of blockages on the signal quality for an open area device-to-device scenario.
We propose a blockage model based on the homogeneous Poisson Point Process. The
model provides the average signal attenuation as a soft metric that quantifies
the extent of blockage. This not only indicates whether the signal is blocked
but also measures how much the signal is attenuated due to one or more
blockers. The analytical results are confirmed with the help of Monte Carlo
simulations for real-world blocker placement in the environment.
