Securing Small Cell Networks Under Interference Constraint: A Quasi-Variational Inequality Approach

Small cell networks are envisioned as one of the critical enabling technologies for the next-generation wireless systems. However, due to the limited capability of small cell base stations as compared with the macro-cell base stations, the secure wireless communication faces significant challenges. Towards this issue, we target at enhancing the wireless security for small cell networks by employing the physical layer security techniques....
