| Millimeter wave (mmWave) networks has been envisioned to satiate people’s growing need for high reliability and low delay of wireless networks. Besides reliability and delay, security in transmissions has also been gaining popularity due to the increasing exchange of critical and personal information. Existing studies mainly focus on the relations between only two of these performances, which is not comprehensive enough for future network design. In this paper, we analyze the relation among reliability, security and delay performance in large mmWave wireless networks, combining the tools of stochastic geometry and queueing theory. Our numerical results reveal that the all three performances get better for larger beamforming main lobe gain, while the increased blockage intensity only improves security performance but degrades reliability and delay performances when legitimate users are far from base stations, which indicates intricate relations among three performances. Our analysis provides important guidelines for designing networks applicable for various demands at quality of services in future applications. |
