Recent advances in wireless networking technologies, along with ubiquitous sensing and computing, have brought significant convenience for location-based services. The localization issue in wireless sensor networks under the non-adversarial scenario has already been well studied. However, most existing localization schemes cannot provide satisfied performance under the adversarial scenario. In this paper, the authors propose three attack-resistant localization schemes, called basic TSCD, enhanced TSCD and mobility-aided TSCD secure localization schemes, respectively, to stand against the distance-consistent spoofing attack in wireless sensor networks.
