Abstract
In spite of having great potential supremacy, device-to-device (D2D) communications are facing lack of implementation in large scale. Insufficient bandwidth with high interference in the micro wave ($\mu$Wave) band is the crucial complication behind it. Enabling D2D communications in millimeter wave (mmWave) band is considered as an alternative solution to these problems. However, line-of-sight (LOS) is a prerequisite for D2D devices to enable links in mmWave bands. In this paper, a distributed method is considered by which D2D devices can detect the existing LOS link for mmWave communication and further perform beam alignment. If there is scarcity of LOS link, this method permits the D2D devices to switch to $\mu$Wave band. Stochastic geometry is considered for system modeling and analysis of this method. Various network criteria such as reference distance, blockage density, frequency, gain of antenna, beam width, density of D2D transmitters, power for D2D and path loss exponents for both LOS and NLOS links are taken into account for analyzing D2D network SINR (signal-to-interference-plus-noise-ratio) coverage probability against SINR threshold. Simulation results reveal that this distributed method has the better coverage probability compared to independently implied mmWave and $\mu$Wave communication.Keywords
