Exploiting User Selection Algorithm for Securing Wireless Communication Networks
2020
How to improve the security and stability of wireless communication systems has become a critical issue. In this paper, physical layer security is introduced to overcome security challenges. The considered communication system is equipped with full-duplex (FD) users in contrast to conventional frameworks where half-duplex (HD) users are at hand. Under these assumptions, we propose a Q-learning based user selection algorithm to model the interaction between a source and multiple users. We also investigate the effect of self-interference and channel interference on physical layer security. The numerical results verify the superiority of the proposed algorithm and in certain conditions, demonstrate substantial performance gain over the conventional approaches.
