Query: A Stochastic Geometry Based Approach to Modeling Interference
  Correlation in Cooperative Relay Networks   Future wireless networks are expected to be a convergence of many diverse
network technologies and architectures, such as cellular networks, wireless
local area networks, sensor networks, and device to device communications.
Through cooperation between dissimilar wireless devices, this new combined
network topology promises to unlock ever larger data rates and provide truly
ubiquitous coverage for end users, as well as enabling higher spectral
efficiency. However, it also increases the risk of co-channel interference and
introduces the possibility of correlation in the aggregated interference that
not only impacts the communication performance, but also makes the associated
mathematical analysis much more complex. To address this problem and evaluate
the communication performance of cooperative relay networks, we adopt a
stochastic geometry based approach by assuming that the interfering nodes are
randomly distributed according to a Poisson point process (PPP). We also use a
random medium access protocol to counteract the effects of interference
correlation. Using this approach, we derive novel closed-form expressions for
the successful transmission probability and local delay of a relay network with
correlated interference. As well as this, we find the optimal transmission
probability $p$ that jointly maximizes the successful transmission probability
and minimizes the local delay. Finally numerical results are provided to
confirm that the proposed joint optimization strategy achieves a significant
performance gain compared to a conventional scheme.
