On Security and Throughput for Energy Harvesting Untrusted Relays in IoT Systems Using NOMA
In this paper, we analyze the secrecy and throughput of multiple-input single-output (MISO) energy harvesting (EH) Internet of Things (IoT) systems, in which a Telephone Antenna multi-antenna base station (BS) transmits signals to IoT devices (IoTDs) with the help of relays.Specifically, the communication process is separated into two phases.In the
