Abstract—Nowadays, many devices require a wireless Internet connection, while the available frequency spectrum is limited. The nonorthogonal multiple access (NOMA) is a multiplexing technology that can significantly improve spectral efficiency and thus solve this problem. In this paper, the use of NOMA in Wi-Fi networks with two traffic types, Web traffic and Internet of Things (IoT) traffic, is investigated. Web traffic is one of the main Internet traffic types. It consists of relatively small data flows that need to be quickly delivered to users. IoT traffic consists of very short data flows compared to Web traffic, but there can be a lot of IoT flows due to a large number of IoT devices. In this paper, we propose an algorithm for resource allocation in Wi-Fi networks with the NOMA. This algorithm takes into account the traffic of both types and its performance is investigated by simulation.

摘要—如今，许多设备都需要无线Internet连接，而可用频谱却受到限制。非正交多址访问（NOMA）是一种复用技术，可以显着提高频谱效率，从而解决此问题。本文研究了NOMA在具有两种流量类型（Web流量和物联网（IoT）流量）的Wi-Fi网络中的使用。Web流量是主要的Internet流量类型之一。它由相对较小的数据流组成，需要快速交付给用户。与Web流量相比，IoT流量包含非常短的数据流，但是由于存在大量IoT设备，因此可能会有很多IoT流。在本文中，我们提出了一种使用NOMA在Wi-Fi网络中进行资源分配的算法。
