On the Limits of Predictability in Real-World Radio Spectrum State Dynamics: From Entropy Theory to 5G Spectrum Sharing
Guoru Ding, Jinlong Wang, Qihui Wu +4
A range of applications in cognitive radio networks, from adaptive spectrum sensing to predictive spectrum mobility and dynamic spectrum access, depend on our ability to foresee th…
Cellular-Base-Station Assisted Device-to-Device Communications in TV White Space
Guoru Ding, Jinlong Wang, Qihui Wu +3
This paper presents a systematic approach to exploit TV white space (TVWS) for device-to-device (D2D) communications with the aid of the existing cellular infrastructure. The goal…
Byzantine Attack and Defense in Cognitive Radio Networks: A Survey
Linyuan Zhang, Guoru Ding, Qihui Wu +3
The Byzantine attack in cooperative spectrum sensing (CSS), also known as the spectrum sensing data falsification (SSDF) attack in the literature, is one of the key adversaries to…
A Game Theoretic Perspective on Self-organizing Optimization for Cognitive Small Cells
Yuhua Xu, Jinlong Wang, Qihui Wu +3
In this article, we investigate self-organizing optimization for cognitive small cells (CSCs), which have the ability to sense the environment, learn from historical information, m…
Distributed Spectrum Access for Cognitive Small Cell Networks: A Robust Graphical Game Approach
Yuhua Xu, Yuli Zhang, Qihui Wu +2
This letter investigates the problem of distributed spectrum access for cognitive small cell networks. Compared with existing work, two inherent features are considered: i) the tra…
Dynamic Spectrum Access in Time-varying Environment: Distributed Learning Beyond Expectation Optimization
Yuhua Xu, Jinlong Wang, Qihui Wu +3
This article investigates the problem of dynamic spectrum access for canonical wireless networks, in which the channel states are time-varying. In the most existing work, the commo…
Load-aware Dynamic Spectrum Access for Small Cell Networks: A Graphical Game Approach
Yuhua Xu, Chenggui Wang, Junhong Chen +4
In this letter, we investigate the problem of dynamic spectrum access for small cell networks, using a graphical game approach. Compared with existing studies, we take the features…
Database-assisted Spectrum Access in Dynamic Networks: A Distributed Learning Solution
Yuhua Xu, Yitao Xu, Alagan Anpalagan
This paper investigates the problem of database-assisted spectrum access in dynamic TV white spectrum networks, in which the active user set is varying. Since there is no central c…
