This article describes about a new approach for securing localization and location verification in wireless networks based on hidden and mobile base stations.The goal of this article is to enable localization with a broad spectrum of localization techniques,
ultrasonic or radio, based on the received signal strength or signal time of flight.Localization and ranging techniques in wireless networks mainly rely on measurements of the time of flight of radio (RF ToF) or time of flight of ultrasound signals (US ToF) and on the measurements of received strengths of radio signals of devices (RF RSS).But,this technique is highly vulnerable to attacks from dishonest nodes and external attackers.Hence,localization relies on a set of covert base stations (CBSs).CBS's are base stations whose locations are not known by the attacker at the time of the execution of the secure localization.By hiding or disguising a static
base station or by the random motion of mobile base stations (MBSs),CBS's can be realized.Hence,they are passive.CBSs can also be used to secure node-centric and infrastructure-centric localization, as well as for localization and location verification in ad hoc and sensor networks.
