Sensor localization algorithms in bestrewn wireless sensor networks
Bin Liu · Computer Engineering and Applications Journal · 2009
Two non-metric multidimensional scaling based node localization algorithms are proposed for bestrewn wireless sensor networks,NMDS-MAP and NMDS-MAP(P).They measure the pairwise distances between nodes with TDOA or other techniques,make use of non-metric multidimensional scaling technique to estimate the nodes location.The former algorithm is centralized,and the later distributed.Simulation experimentation demonstrates that the algorithms are more accurate and robust in positioning sensors.
