Node Positioning Model for UWB Wireless Sensor Networks

Abstract:

A node positioning model of UWB wireless sensor networks is proposed, and positioning error of the model is investigated through simulation. High accuracy of positioning is achieved if all four reference nodes have LOS(Line of Sight) information path, however, even if one reference node does not have a LOS information path, the positioning error will no less than 5 m when the SNR(Signal to Noise Rate) lower than 30 dB, so the SNR or reference node should be increased to assure the positioning accuracy.
