A key element of mobile wireless networks is the constantly changing network topology, which leads to the situation where nodes only have a limited view of the network. As a result, the ground truth for each node is different from other nodes. Thus the nodes have to no option but to make distributed decisions based on their limited view of the network in order to maximize global spectral efficiency. For a network designer, the key question is "How well do distributed decisions perform?"

In this talk, we will review our recent results in answering this fundamental question. The main results quantify minimum amount of network information nodes must possess to achieve global optimal, extent of loss if there information is less than bare minimum and implication on the performance of operational networks. In the process, the analysis sheds light on capacity of some classic hidden-node topologies.
