Abstract

The rapid growth of multimedia applications requiring high bandwidth has paved the way for millimeter-wave (mmWave) device-to-device (D2D) communications. In many modern applications, such as video streaming, same data packets need to be delivered to a group of users. Multicasting these packets has a clear advantage over repeated unicast. Establishing a stable multicast route for mmWave D2D communications is a challenging task as presence of obstacles can easily break a link. In this work we devise a mechanism for constructing a stable route for D2D multicast communications in presence of static as well as dynamic obstacles. This requires some knowledge about the blockage probabilities due to the obstacles. We then present a way of learning these blockage probabilities using the Dempster-Shafer evidential theory framework. We show the effectiveness of our proposed scheme over an existing approach through extensive simulations.
