Abstract
A method implemented in wireless communication systems for finding a topology of a network of communication nodes is presented. The method includes defining a set of the communication nodes as measurement nodes that identify if a channel is available or occupied at a particular time, determining, via a central controller that has access to measurements of at least one measurement node of the measurement nodes, a probability of availability or occupancy of the channel for the at least one measurement node and determining a joint probability of availability or occupancy of the channel for multiple measurement nodes for which a measurement is available, and computing, via a central decision device, the network topology from the determined probabilities.
