Real-Time Rejection and Mitigation of Time Synchronization Attacks on the Global Positioning System
Ali Khalajmehrabadi, Nikolaos Gatsis, David Akopian +1
This paper introduces the Time Synchronization Attack Rejection and Mitigation (TSARM) technique for Time Synchronization Attacks (TSAs) over the Global Positioning System (GPS). T…
Modern WLAN Fingerprinting Indoor Positioning Methods and Deployment Challenges
Ali Khalajmehrabadi, Nikolaos Gatsis, David Akopian
Wireless Local Area Network (WLAN) has become a promising choice for indoor positioning as the only existing and established infrastructure, to localize the mobile and stationary u…
Structured Group Sparsity: A Novel Indoor WLAN Localization, Outlier Detection, and Radio Map Interpolation Scheme
Ali Khalajmehrabadi, Nikolaos Gatsis, David Akopian
This paper introduces novel schemes for indoor localization, outlier detection, and radio map interpolation using Wireless Local Area Networks (WLANs). The localization method cons…
A Joint Indoor WLAN Localization and Outlier Detection Scheme Using LASSO and Elastic-Net Optimization Techniques
Ali Khalajmehrabadi, Nikolaos Gatsis, Daniel Pack +1
In this paper, we introduce two indoor Wireless Local Area Network (WLAN) positioning methods using augmented sparse recovery algorithms. These schemes render a sparse user's posit…
