Method and system for managing communications in a wireless communication network

摘要

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.

1. A method for managing communications in a wireless communication network having a relay-based communication mode operating according to a relay scheme, the network comprising a plurality of network devices defining a plurality of transmission links between them, the method comprising the steps of:
detecting a mobile obstacle distinct from the network devices within the network coverage area; tracking the detected mobile obstacle by iteratively determining a monitoring area within the network coverage area, edges of the monitoring area being some of the transmission links, and the monitoring area including the detected mobile obstacle; selecting, from the transmission links, a subset of links, referred to as monitoring links, belonging at least partly to the monitoring area and monitoring a perturbation level of the selected subset of monitoring links to determine movement of the mobile obstacle in the network coverage area; 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 of monitoring links; determining whether or not the adapted relay scheme provides acceptable load balancing between the network devices with respect to a set of constraints; and in case the load balancing is not acceptable, again adapting the relay scheme with additional constraints.
