Interference and Outage in Mobile Random Networks: Expectation, Distribution, and Correlation

In mobile networks, distance variations caused by node mobility generate fluctuations in the channel gains. Such fluctuations can be treated as another type of fading besides multi-path effects. In this paper, the interference statistics in mobile random networks are characterized by mapping the distance variations of mobile nodes to the channel gain fluctuations. The network performance is evaluated in terms of the outage probability. Compared to a static network, the interference distribution in a single snapshot does not change under uniform mobility models, but random waypoint mobility increases the interference.
