Localization is a basic service and significant technology in Wireless Sensor Networks (WSNs) while in the applications of WSNs, security has become an important issue. Secure localization has thus become a serious issue due to increasing security threats in wireless sensor networks. In this paper, the authors address the problem of making sensors in WSNs locate their positions in an environment in which there exists the threat of wormhole attacks. They propose a distance vector (DV)-based Robust Localization (DVRL) scheme which can fight against wormhole attacks in wireless sensors networks without increasing hardware complexity or incurring too much computational cost.
