Abstract

The present invention relates to a method and system for localization in wireless networks. More in particular, the present invention is related to Received Signal Strength (RSS) based localization in wireless networks. Localization in wireless networks describes the process of obtaining a physical location in an automated manner using wireless communication. Radio Interferometric Localization relies on pairs of nodes simultaneously transmitting unmodulated carriers at slightly dierent frequencies that are highly correlated during the measurement time. Nodes that are within transmission range measure the energy of the envelope of the frequency beat signal. The relative phase offset of the measured envelope of the frequency beat signal at two receivers is a function of the distances between the involved nodes and the carrier frequency. RIPS uses this information to estimate the position of the nodes.
