Abstract:
As 5G mobile communication technologies present new challenges to assuring security and privacy, physical layer security (PLS), which comprises methods to improve data security via physical layer techniques, offers a new pillar of protection. Coordinated multi-point is a transmission technique to enhance signal reception especially for users at cell edges. In this study, we propose a PLS scheme involving CoMP coupled with beamforming and service-based power management. A certain level of geographical isolation for the coverage of the signal for the typical legitimate user is achieved. The proposed scheme is evaluated on simulated scenarios based on real-life mobile network topology data. As a Figure of performance, the secure and successful detection probability is computed with varying antenna array size, number of coordinated transmission points, and different service requirements. The improvement of the area where the legitimate user is vulnerable to security outage is also illustrated.
