关 键 词：Wireless sensor networks Distance correction Node localization Localization accuracy
摘 要：Node localization of wireless sensor network is a hot topic, but current algorithms of 3D wireless sensor node localization are not accurate enough. In this paper, the DR-MDS algorithm is proposed, DR-MDS algorithm mainly calibrates the coordinates of nodes and the ranging of nodes based on multidimensional scaling, it calculates the distance between any nodes exactly according to the hexahedral measurement, introducing a modification factor to calibrate the measuring distance by Received Signal Strength Indicator（RSSI）. Results of simulation show that DR-MDS algorithm has significant improvement in localization accuracy compare with MDS-MAP algorithm.
