论文摘要
Lorawan是一种流行的低功率广泛区域网络技术，在许多情况下广泛使用，例如环境监测和智能城市。不同的应用程序需要各种服务质量（QoS），并且它们在单个网络中的服务需要QoS提供的特殊解决方案。我们考虑了多种需要不同数据包损耗率（PLR）的设备组成的异质洛杉矶网络中QoS提供的问题。为了解决这个问题，我们开发了一个数学模型，可以在Lorawan网络中找到PLR分布。使用该模型，我们表明PLR可能会有很大差异，仅考虑QoS提供的平均PLR是错误的。最后，我们开发了一种用于将调制和编码方案分配给端设备的算法，该端设备提供了低于所需阈值的PLR。
LoRaWAN is a popular low power wide area network technology widely used in many scenarios, such as environmental monitoring and smart cities. Different applications demand various quality of service (QoS), and their service within a single network requires special solutions for QoS provision. We consider the problem of QoS provision in heterogeneous LoRaWAN networks that consist of several groups of devices that require different packet loss rate (PLR). To solve this problem, we develop a mathematical model that can find the PLR distribution in a LoRaWAN network. With the model, we show that the PLR can vary significantly, and it is wrong to consider only the average PLR for the QoS provision. Finally, we develop an algorithm for assigning modulation and coding schemes to end-devices that provides PLRs below the required thresholds.
