An Efficient Technique for Protecting Location Privacy of Cooperative Spectrum Sensing Users
Mohamed Grissa, Attila Yavuz, Bechir Hamdaoui
Cooperative spectrum sensing, despite its effectiveness in enabling dynamic spectrum access, suffers from location privacy threats, merely because secondary users (SUs)' sensing re…
LPOS: Location Privacy for Optimal Sensing in Cognitive Radio Networks
Mohamed Grissa, Attila Yavuz, Bechir Hamdaoui
Cognitive Radio Networks (CRNs) enable opportunistic access to the licensed channel resources by allowing unlicensed users to exploit vacant channel opportunities. One effective te…
Location Privacy Preservation in Database-Driven Wireless Cognitive Networks Through Encrypted Probabilistic Data Structures
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
In this paper, we propose new location privacy preserving schemes for database-driven cognitive radio networks that protect secondary users' (SUs) location privacy while allowing t…
Exploiting wideband spectrum occupancy heterogeneity for weighted compressive spectrum sensing
Bassem Khalfi, Bechir Hamdaoui, Mohsen Guizani +1
Compressive sampling has shown great potential for making wideband spectrum sensing possible at sub-Nyquist sampling rates. As a result, there have recently been research efforts t…
Preserving the Location Privacy of Secondary Users in Cooperative Spectrum Sensing
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
Cooperative spectrum sensing, despite its effectiveness in enabling dynamic spectrum access, suffers from location privacy threats, merely because secondary users (SUs)' sensing re…
Location Privacy in Cognitive Radio Networks: A Survey
Mohamed Grissa, Bechir Hamdaoui, Attila A. Yavuz
Cognitive radio networks (CRNs) have emerged as an essential technology to enable dynamic and opportunistic spectrum access which aims to exploit underutilized licensed channels to…
