Abstract:
Slotted Aloha-NOMA (SAN) protocol is an uncoordinated, non-orthogonal, random access protocol that exploits the simplicity of SA (Slotted Aloha) and the superior throughput of non-orthogonal multiple access (NOMA) and its ability to resolve collisions via use of successive interference cancellation (SIC) receiver. In SAN protocol, the SIC receiver at the IoT gateway adaptively learns the number of active devices (which is not known a priori) using multiple hypothesis testing in order to successfully distinguish between signals transmitted from different IoT devices.

Claim (Index 4):
The method of  claim 3 , further comprising:\n not establishing a connection between each of the active IoT devices and the SIC receiver if the selected optimum power level of each of the active IoT devices is not distinct; transmitting a reselect signal, from the IoT gateway, to each of the active IoT devices to reselect an optimum power level and a receiving antenna; reselecting, by each of the active IoT devices, one of the optimum power levels of the SIC receiver and one of a plurality of receiving antennas of the SIC receiver; transmitting, by each of the active IoT devices, a device identification associated with the active IoT device and a reselected payload, the payload comprising a reselected optimum power level of the SIC receiver and the selected receiving antenna of the SIC receiver; transmitting, by each of the active IoT devices, the device identification associated with the active IoT device and the reselected payload; receiving, at the SIC receiver, the device identification and the reselected payload for each of the active IoT devices; determining if the reselected optimum power level of each of the active IoT devices is distinct; repeating transmitting a reselect signal from the IoT gateway, reselecting one of the optimum power levels, transmitting a reselected payload comprising the reselected optimum power level, receiving the device identification and the reselected payload for each of the active IoT devices at the SIC receiver and determining if the reselected optimum power level of each of the active IoT devices is distinct until the reselected optimum power each of the active IoT devices is determined to be distinct or until a maximum number of attempts has been exceeded; and transmitting, from the IoT gateway a negative-acknowledgement signal to each of the active IoT devices instructing each of the IoT devices to utilize a random back-off in a next transmission of the training sequence over the transmission medium when a maximum number of attempts has been exceeded.
