The Improvement of 3D wireless sensor network nodes localization
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.
