A Localization-Based Anti-Sensor Network System

—In this paper, an anti-sensor network system is proposed, aiming to protect an important area from being under surveillance by an adversary’s sensor nodes. The major components of the system are a set of observing points (monitors) deployed in the area of importance. The observers try to localize sensor positions using antenna arrays to measure direction of arrival (DoA) and received signal strength of the signals emitted by sensors. Once sensors are localized, additional measures are taken to physically remove or disable localized sensors. The proposed anti-sensor network system is designed to handle additional counter-measures that can be employed by sensors, including message encryption and non-uniform transmission power levels. The simulation results show the effectiveness of the proposed system and effects of counter-measures on sensor localization performance.
