  • Patent number: 8005486
    Abstract: Methods and systems for configuring ad-hoc networks, especially a self-configuring wireless sensor networks, are described. The network has an initial number of anchors with known positions that broadcast a signal. The signals are received by distributed nodes whose position is not yet known. The nodes rank the received signal based on a Quality of Link (QoL; received signal strength) and compute a Quality of position Estimate (QoE) for the node. The node with the best QoE is elevated to anchor. This process gradually increases the number of available anchors in the network and hence the position accuracy for additional nodes. The system can be used for geolocation of soldiers in the indoor combat, tracking the location of firefighter and other emergency personnel in rescue missions, etc.
