Localization of sensor nodes is a fundamental and important problem in wireless sensor networks. In this correspondence, a recursive distributed positioning algorithm is devised with the use of range measurements. Computer simulations are included to contrast the performance of the proposed approach with the conventional semi-definite relaxation positioning method as well as Cramér-Rao lower bound. © 2009 IEEE.
