  In mobile wireless networks with blockage, different users, and/or a single
user at different time slots, may be blocked by some common obstacles.
Therefore the temporal correlation of interference does not depend only on the
user displacement law but also on the spatial correlation introduced by the
obstacles. In this letter, we show that in mobile networks with a high density
of users, blockage increases the temporal correlation of interference, while in
sparse networks blockage has the opposite effect.
