In Wireless Local Area Networks (WLANs), the estimation of interference conditions at a receiving node and the determination of interference relations among different wireless nodes is a challenging problem. Interference relations provide the information of which wireless links do interfere if activated concurrently. This information is crucial for the determination of which wireless links are allowed...
We propose a spectrum sharing policy based on signal-to-interference-noise ratio (SINR) at a primary receiver. Contrast to the conventional spectrum sharing policy based on full channel state information (CSI) feedback, in our spectrum sharing policy, a secondary link can share the primary user's spectrum only using a binary state feedback for the interference link between a secondary transmitter...
In practice, a node in a network learns the channel through local message passing and obtains a local view of the network. Pure wireless message passing as well as mixed wireless and wireline message passing are considered in this paper. We study the distributed optimization of sum-rate for a class of deterministic interference networks with local view. A connection based utility function is designed...
