  We study a finite and fixed relative formation of possibly mobile wireless
networked nodes. The nodes apply average consensus to agree on a common value
like the formation's center. %Performance of consensus in terms of convergence
speed is affected by message losses due path loss and interference. We assume
framed slotted ALOHA based broadcast communication. Our work has two
contributions. First, we analyze outage correlation of random media access in
wireless networks under Nakagami fading. Second, the correlation terms are
applied to the so called L2-joint spectral and numerical radii to analyze
convergence speed of average consensus under wireless broadcast communication.
This yields a unified framework for studying joint optimization of control and
network parameters for consensus subject to message losses in wireless
communications. Exemplary we show in this work how far outage correlation in
wireless broadcast communication positively affects convergence speed of
average consensus compared to consensus in the uncorrelated case.
