Exploiting the millimeter wave (mmWave) band has recently attracted\nconsiderable attention as a potential solution to widespread deployment of\ndevice-to-device (D2D) communication challenges, namely, spectrum scarcity and\ninterference. However, its directional nature makes the utilization of mmWave\nband a challenging task as it requires careful beam alignment between the D2D\ntransmitter and receiver. In this paper, we investigate the impact of\ninaccurate angle-of-arrival (AoA) estimation as a beam alignment impairment on\nthe performance of a directional mmWave D2D network. We have used tools from\nstochastic geometry to quantify the signal-to-interference-plus-noise ratio\n(SINR) coverage probability in the presence of beam misalignment, which can be\napplied to evaluate D2D network performance. Moreover, the analytical results\nare verified to be reliable and effective through extensive simulations.\nFinally, the coverage probability of the D2D network with erroneous beam\nalignment is compared to the network with perfect beam alignment. The numerical\nresults indicate that the beam misalignment can lead to significant losses in\nthe network's coverage probability.\n
