In recent years, wireless sensor networks are central to the research activities of the scientific community, particularly given the vast potential applications such as medical care, smart homes, and or environmental monitoring. In the context of wireless sensor networks, the localization technique \"Range-free\" is more efficient with respect to the principle \"Range-based\". Therefore, the authors focused on it. To enable each mobile or normal node to choose its own localization algorithm, they proposed a mechanism adapted by splitting normal nodes in two categories: the first category nodes have at least three neighboring anchors, while nodes the second category have less than three neighboring anchors.
