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.

Abstract: The invention relates to a method of signal analysis that determines the location of a transmitter and to devices that implement the method. The method includes receiving by at least three receivers, from a transmitter, a first continuous-time signal having a first channel. The first channel includes a first plurality of signal carriers having known relative initial phases and having known frequencies which are periodically spaced and which are orthogonal to one another within a first frequency range. The signal analysis method also includes determining the phase shifts of the carriers of the first channel resulting from the distance the carriers traveled in reaching the first receiver. Analysis of the phase shifts yields time difference of arrival information amongst the receivers, which is further processed to determine the location of the transmitter.
