We consider the least-mean absolute, i.e., the ℓ1 norm, minimization of the residual errors and formulate the positioning problem as a difference of convex functions (DC) programming. We then employ a concave-convex procedure to solve the corresponding DC programming. Simulation results illustrate the improved performance of the proposed approach compared to existing methods. © 1997-2012 IEEE.EnglishDC programmingWireless sensor networkConcave-convex procedureD-C programmingResidual errorElectrical engineeringMathematical modelsWireless sensor networksArticle10.1109/LCOMM.2013.020513.122732
