Distributed Coalition Formation Games for Secure Wireless Transmission
Walid Saad, Zhu Han, Tamer Basar +2
Cooperation among wireless nodes has been recently proposed for improving the physical layer (PHY) security of wireless transmission in the presence of multiple eavesdroppers. Whil…
Repeated Auctions with Learning for Spectrum Access in Cognitive Radio Networks
Zhu Han, Rong Zheng, Vincent H. Poor
In this paper, spectrum access in cognitive radio networks is modeled as a repeated auction game subject to monitoring and entry costs. For secondary users, sensing costs are incur…
Cooperative Jamming for Wireless Physical Layer Security
Lun Dong, Zhu Han, Athina P. Petropulu +1
Cooperative jamming is an approach that has been recently proposed for improving physical layer based security for wireless networks in the presence of an eavesdropper. While the s…
Physical Layer Security: Coalitional Games for Distributed Cooperation
Walid Saad, Zhu Han, Tamer Basar +2
Cooperation between wireless network nodes is a promising technique for improving the physical layer security of wireless transmission, in terms of secrecy capacity, in the presenc…
Coalitional Games for Distributed Collaborative Spectrum Sensing in Cognitive Radio Networks
Walid Saad, Zhu Han, Merouane Debbah +2
Collaborative spectrum sensing among secondary users (SUs) in cognitive networks is shown to yield a significant performance improvement. However, there exists an inherent trade of…
