Throughput Analysis for Relay-Assisted Millimeter-Wave Wireless Networks

In this work, we analyze the throughput of random access multi-user relay-assisted millimeter-wave wireless networks, in which both the destination and the relay have multipacket reception capability. We consider a full-duplex network cooperative relay, which stores the successfully received packets in a queue, whose performance are analyzed. Moreover, we study the effects on the network throughput of two different strategies, by which, the source nodes transmit either a packet to both the destination and the relay in the same timeslot or to one of these two by using wider (broadcast approach) or narrower beams (fully directional approach), respectively. We consider the interbeam interference at the receiver and show the optimal strategy with respect to system parameters, e.g., positions and number of the nodes.
