Location awareness for wireless sensor networks has attracted significant research interests in recent years. In hostile environments, there may be malicious attacks to mislead the location estimation of target nodes. In this paper, we discuss the benefit brought by cooperation in the context of robust localization against malicious anchors. Cooperation provides improved detection about the existence of malicious anchors, as well as the ability to estimate their true locations. We also investigate various loss functions and propose an accelerated cooperative robust localization algorithm based on Huber loss function. The proposed algorithm offers accuracy comparable to existing cooperative robust localization methods but at significantly reduced computational complexity.
