ABSTRACT: The problem of finding the location of a node in wireless networks has been a research interest in the last years. In environments where the GPS does not work, the estimation of a node position using only RF signals is not a trivial task. Although some other systems have been proposed so far, using ultrasonic signals, IR, etc. But those require additional hardware that is only to be used for location finding. This article describes an algorithm, which computes the location of a node using noisy distance estimations. Thus, the restriction on distance exactitude can be relaxed and RF signal based distance estimations may be used to estimate the node location.
