Wireless Sensor Networks (WSNs) are based on the technology of sensor; wireless communication, tiny embedded devices, and distributed computing. Localization is the key supporting technology for Wireless Sensor Networks (WSNs). Security and accuracy are the premise of the localization application. Real-world applications of wireless sensor networks are often subject to a variety of adverse circumstances interference, and the localization performance is seriously affected. In this paper, the authors propose a BRS-based Robust Secure Localization (BRSL) algorithm in order to reduce the impact of the malicious attackers in WSNs.
