The authors study the problem of routing/scheduling in a wireless network with partial/delayed Network (channel and queue) State Information (NSI). They consider two cases: a network with a centralized controller with heterogeneous delays from each of the nodes to the controller and with arbitrary topology (thus, the controller has NSI with different delays from different nodes), decentralized routing/scheduling, where each node makes a decision based on it's current channel and queue state along with homogeneous delayed NSI from other nodes. For each of the cases (with additional flow restrictions for the decentralized routing/scheduling case), they first characterize the optimal network throughput region under the above described NSI model and show that the throughput region shrinks with the increase of delay.
