Abstract
In a data processing method for node localization in wireless sensor networks, a plurality of potential coordinate calculation values for a to-be-located node are calculated based on RSSI data received by the to-be-located node from a plurality of anchor nodes. A centroid Cof these coordinate calculation values is calculated. Then coordinate calculation values with distances to the centroid Cless than a threshold are screened out, and a centroid Cof the screened-out coordinate calculation values is calculated. A coordinate position of the centroid Cis used as the position of the to-be-located node. In other words, a plurality of potential positions for the to-be-located node are calculated using multiple groups of RSSI data and these potential positions are then screened through calculation. Instead of directly processing the received RSSI data, the present disclosure processes the coordinate calculation values obtained based on the received RSSI data.
