Center node: "connectivity scaling laws in wireless networks"
  Abstract: We present scaling laws that dictate both local and global connectivity properties of bounded wireless networks. These laws are defined with respect to the key system parameters of per-node transmit power and the number of antennas exploited for diversity coding and/or beamforming at each node. We demonstrate that the local probability of connectivity scales like    $\mathcal{O}(z^{\mathcal{C}})$   in these parameters, where    $\mathcal{C}$   is the ratio of the dimension of the network domain to the path loss exponent, thus enabling efficient boundary effect mitigation and network topology control.
