Distributed relay switching in the presence of dynamic obstacles in millimeter wave D2D communication

adequately. Accordingly, we develop a distributed relay switching (DRS) algorithm, using the local information of the UEs to reduce any further packet loss due to the blockages. Through simulation we show that DRS not only improves throughput and packet loss but also lowers the blockage fraction of D2D pairs and thereby provides higher energy efficiency than the existing approaches which do not consider switching of relays in case of blockage.
