论文摘要
本文调查了非正交多访问（NOMA）增强的物联网（IoT）网络。为了提供连通性，提出了一种新型的集群策略，可以同时提供多个设备。研究了两种潜在的情况：1）NOMA增强的地面物联网网络和2）NOMA增强了空中物联网网络。我们利用随机几何工具来对地面和空中设备的空间随机性进行建模。陆地和空中设备都得出了新的通道统计数据。得出了覆盖概率的确切和渐近表达。为了获得进一步的工程见解，研究了短包通信方案。从我们的分析中，我们表明，NOMA增强的物联网网络的性能能够超过OMA增强的物联网网络。此外，基于仿真结果，存在发射功率的最佳值，以最大化覆盖范围。
This article investigates a non-orthogonal multiple access (NOMA) enhanced Internet of Things (IoT) network. In order to provide connectivity, a novel cluster strategy is proposed, where multiple devices can be served simultaneously. Two potential scenarios are investigated: 1) NOMA enhanced terrestrial IoT networks and 2) NOMA enhanced aerial IoT networks. We utilize stochastic geometry tools to model the spatial randomness of both terrestrial and aerial devices. New channel statistics are derived for both terrestrial and aerial devices. The exact and the asymptotic expressions in terms of coverage probability are derived. In order to obtain further engineering insights, short-packet communication scenarios are investigated. From our analysis, we show that the performance of NOMA enhanced IoT networks is capable of outperforming OMA enhanced IoT networks. Moreover, based on simulation results, there exists an optimal value of the transmit power that maximizes the coverage probability.
