Researchers at ASU have developed a distributed location detection method that reduces power and bandwidth requirements. In this distributed method, each anchor only determines whether or not a node is present within the boundary of its reception and sends its decision to the FC, which then makes a collective decision. Anchor reception boundaries frequently overlap, and the node’s location can be estimated by which anchors detect its presence. Since the anchors no longer transmit complex measurements, less data needs transferred in order to describe node locations. Additionally, this method can detect important node locations amidst interference from other irrelevant nodes.
