摘要

Solving the nonconvex and non-differentiable objective function of traditional range-free node localization methods will result in low localization accuracy or high computational complexity. To this end, a novel iterative localization algorithm called CVX-DV-hop is proposed in this letter. It first performs matrix transformation to reformulate the original optimization problem into one with a conv...
