Although, localization has been widely studied for Wireless Sensor Networks (WSNs), the complex environments and the large network scale pose severe challenges and make it necessary to develop new reliable localization algorithms. In this paper, the authors propose a novel multi-hop localization algorithm for large-scale WSNs in complex environments. This paper is based on the consideration that the localization process would encounter several kinds of adverse factors with different nature at the same time (e.g. anisotropic network characteristics, ranging uncertainty, link quality of multi-hop paths, etc.), which lead to obvious degradation of localization performance.
