Abstract

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 nonadversarial scenario has already been well studied. However, most existing localization schemes cannot provide satisfied performance under the adversarial scenario. In this paper, we 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. The idea behind the basic TSCD scheme is to adopt the temporal and spatial properties of locators to detect some attacked locators firstly and then utilize the consistent property of the detected attacked locators to identify other attacked locators. Enhanced TSCD and mobility-aided TSCD schemes are designed based on the basic TSCD scheme to improve the performance. Simulation results demonstrate that our proposed schemes outperform other existing approaches under the same network parameters.
