| description | With the rapid development of the narrow band Internet of things (NB-IoT) technology,more and more NB-IoT devices are deployed.However,due to the severe co-channel interference and signal attenuation,it is difficult to guarantee the quality of service of NB-IoT devices at the edge.In order to solve this problem,an energy harvesting (EH) relay-aided non-orthogonal multiple access (NOMA) NB-IoT networking model is proposed in this paper.Based on the proposed model,we aim at maximizing the NB-IoT device data rate based proportional fairness through jointly optimizing transmission power,data scheduling and time slot scheduling,to optimize the network performance while ensuring the data rate requirements of each NB-IoT device.By exploring the convexity of this optimization problem,an optimal multi-dimensional resource allocation algorithm based on the KKT conditions is proposed.Simulation results verify the effectiveness of the proposed algorithm,and show the proposed algorithm can efficiently improve the data rate based proportional fairness with 11.9%,the spectral efficiency with 55.4% and the energy efficiency with 44.1%. |
