System and Method for Assigning Mobile Relays in Millimeter Wave Networks
Abstract

This innovation is a method and system for assigning one or more mobile relays to source-destination pairs and intermediate stops in millimeter wave (mmWave) networks, achieving high data rates between sources and destinations. The method involves computing channel gains and data rates, and iteratively assigning relays, if required, to optimize network performance. This adaptive assignment ensures efficient use of mobile relays, mitigating blockage and propagation losses, and improving overall network reliability.
