Wireless Sensor Networks (WSNs) are widely being used in many environments (e.g., disaster relief and target tracking), and WSNs localization is still a crucial research area because of the new localization requirements for emerging application domains such as cyber-physical systems and Cyber-Transportation Systems (CTS). In this paper, the authors review different node localization approaches, and point out the issues and challenges of WSNs localization in emerging applications. First, the measurement-based techniques are introduced, and the range-free localization that is further classified into proximity-based localization, one-hop localization and multi-hop localization, is deeply analyzed.
