Enhancing Secrecy Rate in Cognitive Radio Networks via Multilevel Stackelberg Game
IEEE Communications Letters
In this letter, physical layer (PHY) security is investigated for both primary and secondary transmissions of a cognitive radio network (CRN) that is in danger of malicious attempt by an eavesdropper (ED). In our proposed system, the secondary transmitter (ST) is acted as a trusted relay (TR) for primary transmission and the PHY security is facilitated by the cooperation between the primary transmitter (PT) and the ST using the multi-level Stackelberg game. In particular, we formulate and thendoi:10.1109/lcomm.2016.2541658 fatcat:ibo53csqgnco3iroob5bjjoonm
