The use of Internet of Things (IoT) is becoming increasingly common in agribusiness to increase food production capacity for the expanding global population. Recently, low-power wide-area networks (LPWANs) have been used in the development of IoT applications that require low power consumption and low data transmission rates. LoRaWAN is considered the most suitable communication network for LPWANs for IoT applications in smart agriculture. In this paper, we present an in-depth study of the performance of the LoRaWAN communication network in the context of an IoT application for a pilot farm. We consider several scenarios and analyze simulation results by using Network Simulator 3. We then propose a mathematical model that precisely predicts the successful packet delivery rate for this type of network considering the number of nodes and the transmission interval duration. Finally, we validate the results of our model by comparing them with other simulation results under different scenarios.

物联网（IoT）在农业综合企业中变得越来越普遍，以增加不断增长的全球人口的粮食生产能力。最近，低功耗广域网（LPWAN）已用于需要低功耗和低数据传输速率的IoT应用程序的开发中。LoRaWAN被认为是用于LPWAN的最合适的通信网络，用于智能农业中的IoT应用。在本文中，我们将在针对试验场的IoT应用程序的上下文中，对LoRaWAN通信网络的性能进行深入研究。我们考虑了几种情况，并使用网络模拟器3分析了模拟结果。然后，我们提出一个数学模型，考虑到节点数量和传输间隔持续时间，该模型可以精确地预测此类网络的成功数据包传递速率。最后，我们通过将模型结果与不同情况下的其他模拟结果进行比较来验证模型的结果。
