In large wireless networks, acquiring full network state information is typically infeasible. Hence, nodes need to flow the information and manage the interference based on partial information about the network. In this paper, the authors consider multi-hop wireless networks and assume that each source only knows the channel gains that are on the routes from itself to other destinations in the network. They develop several distributed strategies to manage the interference among the users and prove their optimality in maximizing the achievable normalized sum rate for some classes of networks.
