A Trust Assessment-Based Distributed Localization Algorithm for Sensor Networks Under Deception Attacks

Dear Editor, This letter is concerned with the distributed localization issue for wireless sensor networks subject to deception attacks. It is assumed that malicious nodes randomly launch attacks to tamper the ranging information between sensors. In order to accommodate the effects of deception attacks, a trust assessment-based distributed localization algorithm is proposed. Combined with data fusion of barycentric coordinates, our algorithm can achieve accurate localization. Finally, numerical simulations are given to validate the effectiveness of the proposed localization algorithm.
