The present invention relates to a method for managing communications in a wireless communications network having a mesh or “relay-based” communication mode operating according to a relay scheme. The network includes network devices defining transmission links between them. The method includes initially detecting a mobile obstacle within the network coverage area; dynamically tracking the detected obstacle by iteratively determining a monitoring area including the detected obstacle; selecting, from the transmission links, a subset of monitoring links belonging at least partly to the monitoring area and monitoring a perturbation level of the selected monitoring links to determine movement of the mobile obstacle in the coverage area; and dynamically adapting the relay scheme of the network based on the belonging or not belonging of the transmission links between network devices to the selected subset.
